My condolences.
I sure can relate. My friend killed herself mid August, right after seeing her case manager and assuring him that she would not harm herself.
I've been going through such a mix of feelings also. I really feel for her mental health support team. I'm mad at my friend, sad, shocked, now that time has passed I'm more at peace with the reality.
I like KD's wisdom about making no big changes unless needed. And I'm glad you know that a therapist's job is to help and support you.
