Why me?

I have always wanted to go on a sleepover, but I have always been too nervous or scared to go because I wet the bed most nights. It makes me feel stupid and pathetic, I know none of my friends have ever had this problem they wouldn't understand it. Last time a friend found out, he told the whole school, no one would sit near me or talk to me, like I was contagious. I had to change school.I hate missing out on my school excursion, but a bedwetter doesn't go too good camping, and when my teacher found out why I couldn't go he just laughed. I hate how people think I'm a freak! I don't wet the bed on purpose, it just happens. I feel dumb having to wear nappies to bed at 13 when my little brother is 5 and doesn't have to!
