High-Functioning Anxiety: 5 Signs and Tips to Manage It

High-functioning anxiety often hides behind a calm face, but it reveals itself through restless nights and constant overthinking.

Introduction to High-Functioning Anxiety

I have had several friends who suffered from mental health issues, and my friend Jack was dealing with depression and severe anxiety, which I did not know about. I used to observe his behaviors and reactions with some frustration, asking myself: "Why is he doing this? Why is he acting this way?"

Eventually, we drifted apart, and later one of his relatives told me he was suffering from a mental health condition such as severe anxiety or high-functioning anxiety.

The problem with high-functioning anxiety is that it is not visible externally. To others, you seem normal, living a calm and perhaps organized life. But some people may notice strange actions they don’t understand because internally, you are extremely tense, anxious constantly, and your mind never stops overthinking rapidly and exhausting you all the time.

If you are experiencing these issues and are unsure whether you have this condition, we will explore the symptoms so you can manage and treat them early. Here are the five main signs of high-functioning anxiety:

What Are the Signs of High-Functioning Anxiety?

1. Overthinking

This is when your mind works like a machine, constantly thinking about everything: "What should I do? Why am I doing this? How will I do that?" Your mind creates scenarios, scrutinizes small details, and every time you try to find an answer, new questions arise, often repeating previous questions, making you feel like you are going in circles without reaching a solution.

Even simple decisions become difficult, like choosing what to wear or what to eat today. Every question triggers a complex mental process that you cannot control, and even if you make a choice, you feel dissatisfied with it.

2. Physical Symptoms

High-functioning anxiety is not only a psychological issue but can manifest as physical symptoms. These may include frequent headaches at different times, heart palpitations, and difficulty breathing. These symptoms are common in many medical conditions, which can increase anxiety as people often associate them with other illnesses.

With daily overthinking, lack of sleep, and life pressures, these symptoms become more exhausting, reducing happiness and productivity. Many friends visited doctors to identify the causes, but the usual response was: "There's nothing wrong, you’re fine," despite persistent symptoms.

This happens because doctors focus on physical treatment based on your symptom descriptions. It’s important to describe your symptoms clearly and honestly, so you can be referred to a mental health specialist if needed.

3. Over-Preparation

This is another subtle sign. When starting any project or commitment, even small, you require long preparation time. For example, if a friend invites you to a party, you think: How will I get there? What will I wear? What if I can’t find the right shirt? What if the colors don’t match?

The bigger problem is that your mind convinces you this is careful planning, but it goes beyond. Your mind prepares backup plans and tools for every possible scenario, even impossible ones. In the end, you feel exhausted and cannot enjoy the moment.

4. Fear of Failure

Fear of failure is common to everyone, whether rich or poor, successful or striving to prove themselves. You seek perfection in everything. For example, if you want your company not to fail, you create a successful plan. But with severe anxiety, you pressure yourself to make every plan innovative. The more sales or success you achieve, the more you feel it is not enough, so you push yourself further. Market fluctuations or declining sales increase anxiety as you fear judgment or reputational damage. This cycle increases stress and suffering.

5. Difficulty Relaxing

The last sign is the inability to relax. You may struggle to sleep or even dislike sleep. Personally, I experienced this issue. My mind never stopped thinking, making sleep difficult. Sometimes I would sit on the bed, letting my mind run as if it controlled my thoughts.

Even if I fell asleep for a while, I would wake up suddenly in the middle of the night, only because my mind wanted to resume the chain of questions. Lack of sleep, combined with overthinking, physical exhaustion, and fear of failure, leads to severe fatigue, poor concentration, and may result in breakdowns in relationships and work.

Overpreparing isn't always a sign of productivity; it’s frequently a coping mechanism for the fear of failure in high-functioning individuals.

Important Tips to Manage High-Functioning Anxiety

• Set Aside Time to Rest

If exhaustion is the issue, you first need to stop and rest. Meditate for a few minutes or dedicate daily time for mental relaxation, away from phones or TV.

• Write Down Your Thoughts and Express Your Feelings

If you try to sleep or rest, your mind may attack again. Writing down thoughts helps clarify your mental path and signals your brain that the thoughts have been addressed.

• Define Your Thinking Style

While writing, you may drift from one problem to another without resolution. Define your thinking lines: your goal, what you want to achieve, advantages and disadvantages, and when to say “no.” Break each plan into smaller tasks.

• Exercise to Release Negative Energy

Dedicate at least 30 minutes daily to exercise to reduce stress, negative energy, and release happiness hormones.
