Well, I went to over 4 different ones plus the ones from work. It's me who has to convince myself. My former boss is an asshole he took my perfect stats with him I got nothing he slept with some of the younger girls. I was laughed at, gas lighted, traumatized, bullied and mocked and people were gossiping behind my back. My bosses were calling me delusional. after I sent an email to the top secretary and the deputy prime minister the people left that entire site a week after I resigned from a permanent role and the most safest job you can get. I live in a country which was used as a prison camp I should not be surprised by the bullying involved.
Sounds like a horrid work place, your boss seems a dick and feels like you are right to leave the place. Your co-workers and your boss should be there to help you thrive, not to bully or mock you (only friendly ofcourse). I hope you found some work which will satisfy you and will treat you like a real person.
