Jenny, I know this must me a traumatic situation for you. The first thing I would suggest (aside from not to panic!) is to see your doctor -- I know it will be embarrassing, but one potential cause of sudden bedwetting is a bladder infection, which can be treated easily but could cause more serious problems if untreated. But to answer your question, it's not unheard of for unexplained bedwetting to happen even at this age -- estimates vary from 1/10 to 1% of young adults, which includes many people who contribute to this site. I also occasionally wet at night, and for me being overly tired and under a lot of stress seem to contribute to it, although it's still never quite predictable. The best advice I can offer is not to get too hung up on it... if it happens, it happens, and as Gary said, true friends will understand. You might want to get a waterproof cover for your matress just to keep that safe. If you want to talk more, feel free to e-mail me at spartanadam@hotmail.com. Good luck!
