Hi Rick and welcome...

Jmo, but there isn't much you can really do in this situation. It sounds like you have let her know that you are willing to help if she wants to help herself.
When she gets sick and tired of being sick and tired, she will do something about it...her time line is most likely not going to be yours, either.

Abandonment is not an issue right now, Rick. There is no law, religious or otherwise, that says you have to stay with her, watch her screw up her life, and be dragged into her drama.
It Is All Right For You To Take Care Of Yourself.

Re the counseling...
Call community services in your town/city. If none is available where you live then check out the largest town near you.
I do hope you can talk to someone about your feelings and get advice about taking care of you...

Best wishes,
Cap
