Is OTHER wrong in the post ? POST : So I've know this girl for about 3 years, let's call her C. C and I became friends in school, we were very similar cause we both had terrible family lives and both struggled with mental illness. We where best friends and even dated for a while, she had a hard time making friends cause she was akward and weird like me. During out friendship I noticed some red flags: 

1.she was very unstable and would always treten to kill herself  2. She was obsessed with me  3. She did not take to rejection well. 

These things will come into play later. After a year she randomly left school and I didn't see her for a year, I later found out she was in a school for the mentally disabled and got into self harm and drugs. I had completely forget about her. Since then my life took an entire 180, I got into therapy and medication and got so much better till I didn't even need therapy anymore and I was the happiest i ever been. Then she came back. 

This was about a month ago, she came back talking about how great she was doing and wasn't depressed anymore. Then the next day she told me about how terrible and depressed she was. The reason I wanna cut her out is because she brings me down, and remind me of who I use to be and am not anymore, and I just didn't wanna have to worry about her 24 hours a day. I can't tell her that, one time one person didn't wanna come to her birthday party and she ran to the bathroom and thrented to kill herself, she's done this to me also. Yah she dosent take rejection well. She's such a negative influence, am I an asshole?
