Getting out of a funk

There is a point when you cant go any farther down and I believe I have hit that point now don't get me wrong I do believe shit happens every day but you have to be there to catch it. I have chosen not to catch it any more and that's a good thing take yesterday for example I let my mother my truck it comes back with $2000 worth of repair work I was pissed off to no end then at work I got into it with a douche bag coworker he backed off after I started to yell, after sitting last night up all night I thought what would some of my friends do lets take Drew he would cut a promo on the person make then feel about 2 inches tall so would Hot shot, But then I have friends like Boris who would be pissed off but let it pass Al would be the same. So I took the middle road I yelled and flipped out making her pay for the repairs and then I will let it go I just wont help anyone like it again
