Is it normal i at times get extreme bloodlust?

The right amount of food, water, and sleep works wonders, also try exercise of some kind, and if that's not working, councilling, anything is better than jail, try acting classes to release emotion, yoga, seriously, anything is better than losing it one rainy day. I hope I've helped.

You don't have to worry about jail hunter, usually I just take a vigorous bike ride down the road to cool myself down.

it's times like these ya gotta think of a lemon. Just imagine it in your head all sour and shit, dripping citrus. The sour evocation will surely mute your mind from such thoughts.
