Personally I would go through with doing something so permanent while I was obviously so manic. I have part of a tattoo, not a good story it involves a stake knife, lemon juice and an abusive step father so I wont tell the story. But its not the abuse that I regret the most it's the fact that if I wasn't manic at the time I wouldn't have done it and I wouldn't have this permanent reminder.

Think it through.
