Rap,
Yes it is also incredibly hard for me to do because it's really hard for me to believe any good or positive about myself. One day T told me she thought I was intelligent and I told her I didn't believe her. She looked at me and said so you're calling me a liar?

Which was NOT my intention, it's just hard for me to believe and accept anything positive about myself....
The letter is a good idea too. I didn't think about that. I still think that would be really hard for me to do. I would prob start with the list and work my way to the letter at some point.
