NEED HELP WITH RAGE!

Ok I'm about to smash something over my bosses head! He is 76 yrs old completely lost his shit and constantly blaming people for things they havent done and this morning it was my turn. I'm getting ridiculed , told I do nothing when he has no proof and something he blamed me for had nothing to do with me but if I try to say anything he just yells at me and thats one of my triggers!

God I have gone for a walk, I have tried to calm down but my rage is just going out of control and if I'm not carfeul by the end of th day I will be out of a job if act out! If I could I would tell him where to shove his fricken job but I'm not in a position to do so. I'm fricken HR and he doesnt believe in HR. I know if I wanted to I could easily take them to unfair dissmissal or bullying etc but I dont need that stress. Just when I get on top of myself he comes back from overseas, he has been away for 1 month and then yesterday the second he came in shit starts - I'm not the only one at my wits end but thats all I care about right now.

Sorry Im just venting trying to get out my rage- grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
