You are working in a TOXIC environment and obviously it's taking its toll. You have to get out, or at least transfer to another team. You wrote that you went to HR and they didn't help with your boss, but perhaps they CAN help moving you to another team. And you wrote that you're applying for other jobs - it can take time, just don't give up!

> It's hard for me to believe that another job won't be the same thing It won't be the same thing, because your current boss won't be there! Sounds like he's abusing you, and most likely your next boss won't behave the same.
