What shoud i do ?

Hello I suffer from several problems and I need help and hear some opinions about them.

the first of which is social phobia that prevents me from going to someone and talking to them thats why am here from the first place

I lost trust in me, I feel that my life is being destroyed socially and academically, whenever I want to develop, I stumble and become worse than before, in addition to the depression that kills me, I lost the pleasure of doing everything to the point that there is a girl I liked but I don't have the courage to talk to her I see myself ugly and I hate how weak I am. I hate the person What I became I try to show my true personality but people end up misunderstanding me and this girl is one of them
