How is the best way to end such a relationship, do you think? Just kind of fade away and ignore them?

I used to always be the listener and helper, now it seems I have taken on the role of Debbie Downer, so I try to not whine and complain too awful much to my friends without thinking, or make it always me, me, me.

I try really hard to not be like that all the time, I am aware that behavior mentally exhausts me when people do it constantly. I try and always be there if my friends need to talk or need help, and am generous with time and money. I know, though, that I'm not as cheery and positive as I used to be.

I have a friend who complains constantly. Everything is about her, how bad she has it, and how everyone is mean to her. She is also quite lazy, won't work or cook or clean, and sleeps around. If you have money or a bottle of medicine, don't leave it alone with her. She didn't used to be this way, and I keep hoping she will be normal again, but it never happens. Lol.

I avoid her a lot, don't return calls/texts or say I never got them. I've hidden and pretended not to be home. I feel guilty but she exhausts me.
