Ugh I did it again last night...I masturbated to pictures of girls I know who aren't her on facebook. I feel so bad...I can't help but feel like I'm wronging her and that she deserves someone better than me who won't do this. I feel like I am being dishonest with her in some way. I have a tendency to obsess over things and create problems for myself, but I don't know how to let go of these feelings of extreme guilt...are these feelings justified? Am I being to hard on myself?
