Oh, Toni.
I have a boss but he is not like yours. My boss is more like, you do all the work and I'll pay you a tiny salary. He doesn't yell at me but sometimes I'd like to see him blow up real good.

I know these are serious matters but sometimes a little humor is relief in a world of seriousness.
People say, do this and do that. Its not so easy as that.
I understand what you're going through. Sometimes it seems easier to put up. Maybe, though, you can find a different place to work in time. It could help your sobriety.
