I(F15) have never been diagnosed with it by a specialist because my parents never brought me to a therapist/psychiatrist (they think that therapy is only for crazy people) 

I think that this issue started in March 2020 when quarantine began, probably because I have almost no contact with anyone I used to know (except for text exchanges with 3 of my closest friends) for 6 months.

From what I could find on the internet I have most symptoms of anxiety (panicking out of nowhere in social situations, overthinking, difficulty concentrating on things, problems with sleep, lack of motivation, teribile mood swings, changes in appetite, intrusive thoughts, etc.) 

The problem is that I thinky anxiety or whatever it is getting worse every day. My mental state has been pretty bad in the last few months 

Thar being said, you have any advice that I could use to get rid of this state I'm currently in ?
