Hello people.

I never write this kind of stuff on Reddit but I bring myself to here today. long story short. I've got serious social anxiety recently. my personality and character have been changed during Covid quarantine. I was a very extroverted person and never card of other people saying. But, recently I've suffered heartbroken at the beginning of this year and then I found myself when I confront people my body feels already nervous. I work in the hospitality industry, however, whether my colleagues might like me or not and I kept overthinking what other people might think of me. 

I don't know my brain..... my system keeps fallen into this bad circle the fear of being judged by other people. I don't want to overthink, of course, I want to change this system.

how can I improve? I think I need therapy though, I'm an international student in the UK, so idk how to get access to the therapy session. during quarantine, I had no other deep emotional conversation with others ever. except for my parents, however, I kept telling them "I'm ok, I've been doing great don't worry." so my parents think I',m ok. but I am slowly dying myself.... I would love to make a friend but it's really hard due to covid. I wish I make a friend soon though, sometimes I really want to be isolated or do not want to talk, and being alone is a thing getting used to being for me sometimes....

but I do want to change myself. 

so the problems are,

1. keep coming panic attack that I think I was being judged by other.
2. endless overthinking recently.
3. social anxiety.

if any advice for me as really struggling to live alone here in the UK, I really appreciate your comments. 

thank you in advance.
