Oh, my, how sad. Please know that she ultimately made her choice, and we don't know that your trying to help would have even worked. Have you considered talking to a therapist about any guilt you're feeling?

By the way, we on these internet sites should not be expected to try to "save" people from themselves and Psych Central has an official policy for people to not post such "threats" about that. We are not professionals. And even professionals aren't successful all the time. Okay? Please try to get yourself out of thinking that you were responsible for not being there. It's a sweet letter, though. And I wish she could read it. I think she would take you off the hook if she could.
