look bro, i can relate, i've been the same way. More than likely you are just upset about your dad's condidtion- which is understandable. I'm not here to tell you not to do nething stupid or anything like that, you know better. But, sometimes you just need to vent on someone, find someone you trust, and talk to them. Preferably someone from the opposite sex, girls seem to understand alot more than guys.
