I am the same way. I always feel I need reassurance in things, or feel like I done something bad when usually I haven't done anything bad but I feel I always do so I hear ya :/ I need to re-check emails, etc. too as well.

I know this sounds silly but I had a really bad obsession with psychics :/ Because I just wanted to so badly know if I was doing the right thing, is everything going to be okay, etc.
