Do you think I have a problem?

I'm 13, and have been a bed-wetter for 2 years. I've been using GoodNites to keep the sheets dry. I still can't stop it. I wake up every hour to pee. Sometimes I do, sometime I don't but I try too. I drink water before I go to bed then pee so that I can get all the water out. It's hereditary, (through my aunt) She had it for 4 months? Will I continue forever. I'm also scared I might get a urinary trac infection, because I can't pee at school. Is it because I'm scared too, or I just can't pee?
