I used to have the feeling that I needed to go to the bathroom constantly. I never really had any need, but I still felt that i had to go at least once an hour, every recess at school and so on. Especially when I was about to go to bed. It got pretty bad for a while, where I'd go 10 - 20 times before I finally went to sleep. If I didn't, I'd get more and more anxious until I was nearly panicking. I dunno why that was...it went on for a while, though I can't remember for how long, and then it gradually faded out, thankfully.
