Thanks for the responses!!!

So, as for my mother getting help, she actually has that well covered. She sees a therapist as well as goes to group therapy sessions. She also has a Psychiatrist.

The problem came in, when she told the people there about the issues she was having with her roommate, and instead of addressing her emotional issues, they simply told her to call the cops if it got out of hand, which only scared her more, thinking she might have to call.

I saw this as when I needed to step in and help. I didn't realize that advice to call the cops was supposed to help. Now I see that is exactly where the boundaries should've been put.

My only issue now, is simply that I know what I know. Sometimes just knowing how far the rabbit hole goes for her is just too much for me to bear. Growing up, I was exposed to about 60% of it, but now as an adult, I see about 90% of it.

How does one cope with simply knowing?
