You don't have to be 18 to be as crazy as this chick. I know women in their 30s that drive by their boyfriends job just to see if he's really there lol Good luck to your therapist OP, hopefully he'll be like that doctor in A Clockwork Orange and he'll jam pack a bunch of images of your friend in a happy relationship so you could get that in your head and move on and join Halle Berry, Adele and the rest of the women who can't find success in relationships.
think of it as alession learned on your journey though life Ull feel mortified for a month or so But in the long run its going to blend in with all your other memories. Good and bad Next time, try thinking about tomorrow that's what I try to do
