Anger Managment Needed

This is how I feel when drawing, all the time... When the picture doesn't turn out the way you want it too... You just want to destroy something (Mainly, my computer, since it's in front of me). You know what I mean?! That rising anger or frustration??
I just had to draw this, b/c I quite drawing 2 other pics, I was getting so angry. So, I drew this to get rid of some of it, so please, no critisim... Comments are allowed still of course.

My poor computer, it's just an innocent victim...
