What Is the Difference Between Anxiety and Depression? What You Need To Know

by | Dec 6, 2023

We’ve been thinking about how often people mix up anxiety and depression. They’re like the two most common mental health issues we hear about, right? But even though they sometimes hang out together, they’re actually quite different. It’s like mistaking a crocodile for an alligator — they seem similar, but there are key differences.

In this blog, we’re going to dive into what sets anxiety and depression apart. It’s important to get this right because it affects how we treat them. We’ll chat about the emotional and physical symptoms, how they mess with your thinking and behavior, and why sometimes they decide to tag team.

Plus, we’ll cover how to tell them apart when they decide to crash the same party and what we can do about it, treatment-wise. We’ll also touch on TMS therapy, which is doing wonders for both anxiety and depression.

So, grab a coffee, get comfy, and let’s break down the mystery of anxiety vs. depression. Understanding this stuff is a total game-changer. Let’s get started!

Understanding anxiety

Let’s break down how anxiety works. Anxiety is like your body’s natural alarm system. It’s supposed to help you stay alert and aware, especially in stressful situations. Think of it like the body saying, “Hey, watch out. You need to be careful here.”

But when someone has an anxiety disorder, it’s like their alarm system is way too sensitive. It goes off when it doesn’t need to. For example, it might be a presentation at work or even meeting new people — everyday stuff for most people, but the anxiety response is as if they’re facing a major crisis.

Physiologically, what’s happening is your brain starts firing off all these signals that ramp up your sympathetic nervous system — that’s your “fight or flight” response. Your heart rate goes up; you might start sweating, feel jittery, or get an upset stomach. It’s your body prepping for danger, even when there’s no real danger around.

In the brain, it’s more complex. There are a few areas, like the amygdala, which is kind of an alarm center, and the prefrontal cortex, which helps you rationalize things. With anxiety, the amygdala is overactive, and the prefrontal cortex doesn’t always do a great job of convincing you that, “Hey, it’s okay. There’s no lion about to chase you.”

Understanding depression

Understanding depression

Now, let’s talk about depression. When someone’s depressed, it’s not about feeling really down. They often lose interest in stuff they used to enjoy, feel constantly tired, might struggle with sleep, or find it hard to concentrate. It’s like the color gets drained from life. They might feel hopeless, like things will never get better.

Biologically speaking, depression involves changes in brain chemistry. The serotonin and dopamine that regulate your mood, appetite, and sleep get all out of whack. It’s not about having a bad day; a significant shift in the brain’s chemistry affects how you feel and perceive the world.

One of the toughest parts of depression is that it creates this cycle. You feel too drained to do things, but the less you do, the worse you feel. It leads to a downward spiral that’s hard to break out of.

But the good news is, it’s treatable. It might involve therapy, medication, lifestyle changes, or a mix of these. The big thing to remember is that it’s a real medical condition. It’s not a weakness or something you can snap out of. If you had a broken leg, you wouldn’t expect that to heal without help, right? Same with depression.

Key differences between anxiety vs. depression

There are differences in how anxiety vs. depression affects you emotionally, physically, mentally, etc. Let’s take a closer look.

Emotional symptoms

With anxiety, it’s like your mind is constantly on high alert. You’re often worried or scared about stuff that will happen, even everyday things. The world feels dangerous, even if you’re not in any danger.

Depression is more like a feeling of being stuck in a deep, dark hole. You’re sad, don’t enjoy things you used to, and might feel hopeless. And sometimes, you can’t feel at all.

Physical symptoms

Anxiety often shows up as feeling jittery or restless, feeling your heart racing, maybe sweating a lot, or feeling queasy.

With depression, it’s more like you’re always tired, your appetite might change, and your sleep’s all over the place. You feel drained.

Thought patterns

When you’ve got anxiety, your brain is like a hamster on a wheel, always expecting the worst, and you can’t stop worrying.

If you’re dealing with depression, your thoughts get really negative. You might feel worthless or guilty, and focusing or making decisions is tough.

Behavioral changes

Anxiety might make you avoid things that freak you out. Some folks even develop specific routines to manage their fears and avoid things that could trigger their anxiety.

If you’re depressed, you might pull back from hanging out with friends, stop doing your hobbies, and generally slow down.

How it impacts everyday life

With anxiety, you’re often on edge and can’t relax, making everyday stuff feel harder. Depression makes you feel like you’ve got no energy or motivation, so even simple things can feel overwhelming.

When it happens and what triggers it

Anxiety tends to pop up in certain situations or because of specific thoughts. It can come and go but can also stick around.

Depression is more like a constant background noise, affecting a lot of things for a longer time.

Getting better

It’s possible to treat anxiety and depression, but they do need different approaches. Anxiety might need more strategies to manage stress, while depression might need more strategies to help you feel motivated and positive. Learning to reframe thoughts, therapy, and sometimes meds can help with both.

Co-occurring and overlapping symptoms

Co-occurring and overlapping symptoms

Alright, so when we talk about anxiety and depression, it’s pretty common for them to crash the same party — meaning they can show up together in the same person. This makes things a bit confusing because they share some overlapping symptoms but also distinct differences.

The overlapping stuff includes things like trouble sleeping. Whether it’s anxiety keeping your brain on high alert at night or depression making you feel too down to get out of bed, both mess up your sleep big time. 

Then there’s the whole energy thing — feeling super drained is common in both. With anxiety, it’s like your battery gets run down from all the worry. With depression, it’s more like your battery isn’t charging up in the first place.

Concentration is another tricky area. Anxiety might have your thoughts jumping all over the place like a pinball, making it hard to focus. Depression, on the other hand, will make your brain feel like it’s in a fog, so focusing on anything becomes a chore.

Both also mess with your appetite but in different ways. Anxiety might leave you with a stomach in knots and not feeling like eating. Depression will either kill your appetite or make you turn to food for comfort.

Now, while these symptoms overlap, the core feelings are different. Anxiety is rooted in fear and worry about the future, while depression is more about feeling empty, hopeless, or not finding joy in life.

It’s like having two different radio stations playing at the same time — both are loud, but they’re playing different tunes. That’s why it’s tricky to figure out if it’s anxiety, depression, or both. But understanding these overlaps helps a lot in understanding what someone’s going through and finding the best way to help them.

Diagnosis and treatment approaches

The first step is getting the right diagnosis. For both anxiety and depression, a doctor or a mental health professional will usually start with a consultation — they’ll ask about symptoms, how long they’ve been around, and how they’re impacting life. They usually use specific questionnaires or checklists

Sometimes, they’ll do a physical exam or run some tests to rule out any other medical conditions that might be causing symptoms.

Treatment approaches usually look something like this

Treatment approaches usually look something like this:


  • Medication: Things like antidepressants and anti-anxiety meds can be helpful.
  • Lifestyle changes: Exercise, meditation, and other stress-reduction techniques often make a big difference.


  • Therapy: Again, CBT is really effective here. There are also other types of therapy, like interpersonal therapy or problem-solving therapy.
  • Medication: Antidepressants are often used. You’ll want to find one that works with minimal side effects, so you usually need to shop around before you find a good fit.
  • Lifestyle adjustments: Regular exercise, a healthy diet, enough sleep, and sometimes, light therapy.

How TMS therapy helps both

Okay, let’s talk about TMS therapy and how it’s helping out with both anxiety and depression. It’s pretty cool stuff.

Think of TMS as a bit like a targeted workout for your brain. It uses magnetic pulses to stimulate specific parts of the brain. 

Now, in both anxiety and depression, certain areas of the brain are a bit off in terms of activity. With depression, some parts that regulate mood and emotions might be underactive. With anxiety, there are areas that go into overdrive, causing all that worry and fear.

So, you sit in this chair, and they place a magnetic coil on your head. Don’t worry — it doesn’t hurt or anything. This coil sends magnetic pulses that stimulate those specific brain regions we talked about. The idea is to jumpstart them back into a healthier pattern of activity.

For depression, it’s like waking up areas of the brain that have been a bit sleepy. People often find their mood lifts, they get more energy, and life starts to feel a bit more colorful again.

With anxiety, it’s more about calming down those parts that are in hyperdrive. It helps reduce that constant sense of worry and helps you feel more relaxed and less on edge.

The best part? You don’t have to worry about the side effects you often get with meds, like weight gain or feeling numb. And it’s non-invasive without surgeries or anesthesia. Simply chill out and listen to music or meditate or whatever while you’re doing it.

TMS often works best when combined with other stuff like therapy, and it might take a few sessions before you start noticing a difference. For a lot of people, TMS is a real game-changer in managing anxiety and depression.
