For what it's worth, I don't think there are horrible people, or horrible friends. We all have our own struggles to deal with, and it just shapes us differently. You seem like a very kind and loving person with a big load on her shoulders. Most friends come and go, and that's natural. You have to be friends with yourself first and foremost. That doesn't mean you have to be lonely while you do it, just take a deep breath and recognize that you must be your own best friend.

On another note, I'm on lexapro too. I'm not sure it's doing squat, but I'd be interested to hear your feelings on how your meds are working.

Take care, ss. *hug*
