What's Your Preferred Cure when you are in one of those "moods"

where you just want to tell almost the entire world to go F themselves, but you know you can't really do that?

I am in one of those moods. I am sick of the pukes, I am sick of this country being sold to the highest bidder, I am sick of family telling me to just let things go,

I am sick of people who don't do what they are supposed resulting in me getting bitched at by others in public who expect me to magically step in and fix the other persons screw up even though it's a volunteer position, and I wasn't even supposed to be a part of the project to begin with, just the messenger.

That later is real issue with me because I have this happen to me again and again, in high school, in college, on the job. In fact in terms of jobs that was one of the key issues in me having a nervous breakdown and ending up on disability.

I've heard the same thing all my life "Oh she won't mind, she will do my work too if I ask her, she's so responsible," and like an asshole I do it because I was raised by parents who said "you never say it's not your job, you just do it, " but the minute I can't handle my responsibilities and theirs, it's jump down my throat time.

People keep telling me "oh your such a nice person, such an innocent person," well all that gets me is being taken advantage of and I am getting sick of it real fast. I used to just put up with it and do it to avoid conflict but I am sick of all of it. Plus they don't know in my head that I am telling them to just go you know what themselves.

I need a safe way to vent any suggestions?
