Well then you must be thinking something is too wrong in you? But people don't really care that much...most people won't even notice anything about you but some people will. Unless they consider you as threat they will not care much to notice everything about you. People don't have that much time and energy. Just notice yourself, do you look at every person and notice everything about him/her? The thing is your brain has created this fear and it's intensity is high, but it is a false alarm...if you will go out you will realise it.
But It has already happened with me people judged me and also made fun of me that's why I am afraid. My hands literally shivers whenever I try to go out.. this anxiety sucks man..
Ok but what has their judgement caused you? Physically you are safe and mentally you are capable of changing. If you think what they are judging about is significant please go ahead and try and change for your own good, but they are judging for nothing they please learn to ignore people. Not everyone's opinion should matter to you. Be selective whose opinion and judgement you will take seriously in what conditions.
And also I am suffering from extreme social anxiety btw thankyou so much to respond
