I feel like garbage bin

Moved to new city super toxic workplace and abusive people. It's now like 6 months I'm here and feels like I'm in prison. Not able to do anything not able to comprehend anything. I was f extrovert head of frat for 2 years super cool jobs and gpa it was dream life hardly any debt. Now everything is exactly opposite not even made 1 contact in 6 months. Now I'm sick like anything can't nice and I'm realizing how big looser I'm in reality. I know if I'm not getting cured I'm dying in random place and no one will even notice my death
