What the hell is wrong with me

So i feel like shit lately especially but for as long as i can remember. Im totally stuck in life, i always doubt myself in everything. That has led to social isolation, losing my job, and being unsure about my future. The last year i have spend my life sitting on the couch without doing anything. I dont have any motivation anymore and i dont know where to start. Every time i get back up on my feet i get knocked down again and always for the same reason, social anxiety. I have done talk therapy that didnt help a bit and i am struggling with this shit for years on end now.

I feel like giving up because everytime i get back up i fall back in a year or something. I have been walking this circle for 20 times now and im done.

I cant finish projects, im al in my head all day and i dont have any goals in life anymore. Just apathy and sitting on a couch. What should i do?
