I've known her for two years. She's never been on the right meds, hates her doctor, doesn't work because of welfare checks, and she gets kicked out of every home she lives in. She is currently residing on the railroad tracks with her new boyfriend and claims she's never been happier.

We were best friends but whenever we hang out her mood swings are off the chart and it's incredibly stressful to be around her. I've tried helping her many times and bought her a self-help book. I just decided that enough was enough. I wasn't happy hanging around her when she was spun and I didn't want to be around that type of behavior. At that point I decided I couldn't be friends with her any longer.

We were on facebook and I was very brief and said "im someone who worries and honestly I think I am going to worry too much about you to be worth being friends with. I'm sorry, but even hanging out with you is stressful and I can't handle it. Goodbye." I blocked her and then started sobbing.

I feel devastated. I care for her and I love her, but I can't handle her emotions and I don't want that kind of person in my life anymore. I'm sure there was a better way to end our friendship but I just needed to do it and couldn't think of a better way to do it. I talked to my dad and he made me feel better, but I have pictures of us on our wall and I don't want to throw them away. We had so many fun memories and I don't want to just "Ctl+alt+delete" her from my life. She was important to me.

I've never had to end a friendship with a best friend. I feel so devastated. I don't have many friends to begin with. What should I do?
