How to manage anxiety, overthinking, and mental exhaustion

Lately, I’ve been reflecting on how often clients tell me that they feel mentally and physically exhausted. They describe having little energy, overthinking even the smallest decisions, and feeling constantly overwhelmed by everything they need to manage.

Over time, that mental strain can begin to show up in the body. You might notice muscle tension, headaches, an upset stomach, a racing heart, shallow breathing, restlessness, or difficulty falling or staying asleep. Even when you finally have a chance to rest, your mind may continue replaying conversations, anticipating problems, or running through tomorrow’s to-do list.

I know that, for me, this pattern used to show up regularly as self-doubt and feelings of impostor syndrome. I didn’t think I was worthy or good enough. I constantly compared myself to others and even looked for validation and happiness everywhere but inside myself. You may be wondering what these experiences have to do with anxiety or overthinking, but consider what happens when you repeatedly replay conversations, compare yourself to others, or question whether you said or did the right thing. Over time, this constant self-questioning can begin to affect your confidence and make it harder for you to show up in the way that you want.

So why are so many of us experiencing the same struggle and what can we do about it? First let’s take a look at why our minds overthink in the first place. 

Why does your mind keep overthinking?

Overthinking, sometimes called rumination, is often an attempt to create a sense of certainty or control. Your mind may believe that if you analyze a situation long enough, prepare for every possibility, or replay a conversation one more time, you will eventually arrive at the “right” answer.

Instead, you may find yourself caught in an exhausting cycle:

  • You encounter a stressful situation or uncertain decision.
  • Your mind begins searching for possible problems.
  • You question your choices and imagine different outcomes.
  • Your body responds as though there is an immediate threat.
  • You become mentally and physically drained.

This cycle can be especially familiar for people who are highly responsible, self-critical, perfectionistic, or accustomed to taking care of everyone around them. You may appear capable and calm on the outside while on the inside you feel as though your mind is on overload.

Overthinking may be a sign that your mind and body have been operating in a heightened state of stress for too long.

Signs that anxiety is becoming mentally exhausting

Anxiety does not always look like panic. Sometimes it appears in quieter, more persistent ways.

You might notice that you:

  • Replay conversations and worry that you said the wrong thing
  • Struggle to make decisions because you fear making a mistake
  • Mentally prepare for situations that haven’t even happened
  • Feel guilty when you rest or are not being productive
  • Have difficulty concentrating or completing simple tasks
  • Wake up feeling tired, even after sleeping
  • Feel irritable, emotionally drained, or easily overstimulated
  • Carry tension in your jaw, shoulders, neck, or stomach

These experiences can gradually become so familiar that you begin to think they are simply part of your personality or over time they become so ingrained in your “own Story” and point of view that you begin to believe they are “normal”.

First, it is important to know that you are not alone. We live in a world that can feel demanding, overstimulating, and anxiety-provoking. Many of us are expected to manage work, relationships, family responsibilities, and an endless stream of information while still appearing as though we have everything under control.

The good news is that small, intentional changes can make a meaningful difference. Over the years, I have learned that I cannot take on too many changes or challenges at once. I have also learned that what helps me may not be what helps you and that is okay.

Start with one small step… A Pause. A breath… Even being kinder to yourself. Here is something that can help.

Try the STOP Technique

When your thoughts begin moving quickly, you may feel pressure to solve everything immediately. The STOP technique can help you interrupt that automatic response and create a brief moment of space.

Visualize a stop sign and use the following steps:

S: Stop

Pause what you are doing, if possible. You do not need to respond, decide, or solve the problem at this exact moment.

T: Take a Breath

Take a slow breath in and allow yourself to fully exhale. You do not need to force yourself to feel calm. Simply notice your breathing and give your body a moment to slow down.

O: Observe

Notice what is happening within and around you.

Ask yourself:

  • What thoughts are running through my mind?
  • What emotions am I experiencing?
  • Where do I feel tension in my body?
  • Am I responding to what is happening right now, or to what I fear might happen?
  • What do I need in this moment?

Try to observe without criticizing yourself or immediately trying to change the experience.

P: Proceed

Finally, choose your next step with intention. This could mean returning to the task, taking a short break, asking for support, setting a boundary, writing down your thoughts, or deciding that the situation does not need to be resolved today.

The STOP technique will not eliminate every anxious thought. Its purpose is to help you pause long enough to respond more intentionally instead of automatically reacting to anxiety.

Begin with one small change

When you already feel overwhelmed, a long list of coping strategies can become one more thing you feel responsible for doing correctly. Instead, choose one small practice that feels realistic.

You might:

  • Use the STOP technique once each day
  • Write down a worry rather than continuing to hold it in your mind
  • Choose your three most important priorities for the day (your 3 non-negotiables)
  • Take a short break from your phone or social media
  • Create a calming routine before bed
  • Ask yourself, “Does this need my attention right now?”

Small changes may not feel dramatic, but they can help you begin rebuilding a sense of safety and trust within yourself. You do not have to address every concern at once to start feeling better.
