I was in a similar situation. Here are my advice: 1. It's just him. Some people are just a-holes. You need to leave. Not all jobs are like that, not all bosses are like that. Abuse is abuse. 2. When I was in your situation, I focus all of my energy to learning a new skill. It's as if I used all that I hate about this job to motivate myself in learning something new. It worked.

Best of luck
