It's rough but you'll get through it, Blake. I'm sorry but "My own problems just got in the way I guess" doesn't cut it. I'm glad she wasn't abusive toward you but she is trying to guilt-trip and manipulate you. Like I said, I hope she gets the help she needs but it's not your problem anymore.
Sending huge HUGS your way. You are going to be okay. You're already well on your way.
