I just left my friendship of 7 years with my best friend who has borderline personality disorder along with schizophrenia, bi-polar, major depression, anxiety and panic disorder. She denies having any of these issues and refuses to get help. She told me she would only get help if I am there with her as support. I don't know if I can handle anymore from her. She is manipulative, treated me like total crap and so on. On her good days/hours, I couldn't be happier with her as my best friend. Otherwise, it was so bad. I feel terrible for leaving and maybe giving it another shot since she said she'd go through therapy and get help. I don't know if I should or if it is just another way of her manipulating me. Any thoughts/words of advice would be great. Its the hardest thing I've had to endure in life (so far).
