Visual Art Trouble...

A very tiring and busy day, I kept on painting on the same spot on the canvas for a long time...I was really a mistake I shouldn't have done. But all I coud do now is to do as much as possible but the more I think about my art work I feel like a loser. What do I do now? I hate myself for what I have done, why I always have to cry over spilled milk? I am so silly...I guess I will be stuck in this stupid cycle...So I guess now I better scram off and do my art piece and preparetory work before I am in deep deep deep SHIT!
