I hope I can say this nicely and that you'll only take it how I mean it. But you haven't been out of the house in a decade and you can't stand a single person at your job - it sounds like you might have some issues with people in general and maybe some anxiety, anger, or something else. No judgement here and I don't know your situation.

I will say this: there are indeed really shitty, toxic, selfish, and narcissistic people out there. But most, probably the majority, are people just like you. They have their own anxieties, fears, doubts, idiosyncrasies, etc. They make mistakes and try their best to be happy and stay safe.

I guess I would say just cut them some slack. Be someone they can feel safe and happy around. Don't judge them too harshly. "Lest ye be judged yourself" and all that.

Good luck though. I hope you find at least one good friend at work.
