I think I probably have OCD too, I regularly go back and check I've shut the field gate and stable doors even though I know I've already done it. I do stop myself most of the time but it's certainly a compelling feeling to.
Oh anne I'm sorry..I didn't mean to make light of your situation. . Having said that though I think we all have a form of ocd :( I wash my hands more than needed!
If money goes missing, and the bank find out you have given your PIN number out, they will refuse to compensate.
This is irrespective of who takes the money.
