But looking back on my past I think part of the problem was when I was little. I once went to my Grandad's house, as we did on a regular basis, but i always found it really boring! There was just nothing to do. So this one time I went to the toilet, just for a wee, but my Grandad walked in on me just when I was killing some time just sat leaning forward on the toilet thinking about random things that go through a 7 year olds head. From that day I always worried that my Grandad thought I was goin for a poo.
I can't say that this is directly when my problem started, but I don't think it has helped.
But I'll keep thinking.
