Dear Abby: How can I protect my mentally ill daughter’s children?

DEAR ABBY: My daughter, “Aline,” 40, has gone from crisis to crisis since childhood. She can go from kind and generous one minute, to vindictive and mean the next. She’s easily triggered into rants, hurling the most hurtful words she can come up with. Men move in and out of her life on a regular basis.

I’m sure Aline would qualify as mentally ill, but she insists she’s too smart to go to therapy -- she knows more than they do. I have become exhausted dealing with her. She believes everything is my fault. I’d walk away if I could.
