It sounds like you are able to see when a situation is indeed unhealthy, and remove yourself from the situation.

If I had a friend like yours, I would probably exit the friendship myself. I know that people have all sorts of struggles in life, but I don't want to be around people who aren't trying to better themselves when things go wrong. I mean why should I give them "support" when they won't even "support" themselves?

I think you're right in wanting to end things with your current friend. There's only so much you can do for another person.

I think that you'll be much happier when you have friendships that are more balanced. It can be hard to find these sorts of friendships, but they are indeed out there. I think its good to take things slow when getting to know a good friend, that way you can evaluate things as you go and not end up in over your head so to speak.

Just remember, friendship is always a two way street. Of course there will be times when one person needs more support and cannot give as much support, so that's why its important to look at the overall picture----and I think you have done just that. Its not so much that your friend is in a bad spot and needs support while she works things out....she's freely admitted that she's in a bad place and has told you that she won't ever get out of this bad place. I think that does indeed put a lot of strain on a friendship, as it makes it an unbalanced relationship. Hugs.
