I can't believe any DECENT person would say someone else is a "waste of space." Maybe these other folks don't see the side of her you saw. Or she gives them something they need somehow.....

I agree with the other folks. No one deserves to be treated the way she has treated you. I can understand how you would take that to heart, but I agree that you must realize that she does have a problem.

Are you in therapy? I ask because I'm a firm believer in it, and I think it would help you to feel better about yourself, treat yourself better, and ultimately attract healthier, more decent people into your life.

You might have to be in some of the same circles with her, but you can try to keep your contact at a minimum and seek other good places for companionship. I suspect you might have been abused in some way as a child (as many of us were), and so it's easy to accept other people's negativity about you and fit that into your low opinion of yourself.

I just finished reading a book on this type of subject, so my thoughts are related to that. (My self-esteem isn't as good as it needs to be, so I'm trying to work on it.)

I'm distressed that you are having to deal with this issue. Life is tough enough as it is. But I do think you can have much hope that the future can certainly be better!
