The Voices in my Head

I have always been very critical of myself and one of my biggest arguments is when I don't do something the best it could have happened. I am a huge perfectionist and I have always been very hard on myself and when I do something below perfect I get extremely angry at myself. I probably have this argument with myself about twenty times a day. I just feel like sometimes in my head I put these huge standards on what I need to do. Then it stressed me out and then it puts a huge toll on my body. So in the end I win and lose the fight because I make myself feel like crap for the work I've done...but then in the same turn I suffer the stress.
