It’s a question that most anxious people receive from others, and is a question that anxious people ask themselves as well. And to be completely honest, much of the time I don’t know why either, I’m as clueless as you are.
It is a question that is annoying to answer, as you are describing a feeling and sensation that is so intense and is something that isn’t visible. Talking about my anxiety feels as though I’m trying to explain how a ghost can move objects, people need to experience it or visually see anxiety to understand it. That is probably the exact reason why I am asked why I feel anxious, someone is trying to gain insight into what it feels like and why it exists for me, but it is immensely difficult to justify my anxiety when I don’t even know myself.
I shouldn’t have to prove my anxiety and why it appears, I don’t have to know the answer and either do you. Not everything has its answers, and I’m still trying to come to terms with the realisation of not knowing why my anxiety is a constant occurrence.
One thing I have learnt from the last year is that anxiety doesn’t need an exam or a dentist appointment for it to have an excuse to come to the party. Anxiety for me is worrying excessively if I’m going to trip over my feet in public and stutter on my words. You might be thinking that I must do those things frequently but I haven’t once, it would make sense though if I had, but not everything can have an explanation.
However, not everyone is trying to understand why someone is anxious. When they hear that someone doesn’t know why they are anxious or even when they are given an explanation, most people are told that they are over exaggerating, overthinking and overreacting. Being told you’re just dramatic about your feelings doesn’t make them suddenly go away surprisingly, although makes the feelings seem not logical, making the situation worse.
Maybe instead of asking someone why they are anxious, ask how you can help. That way you can actively help towards solving the issue.
