Hi, I also happen to have a friend who is exactly like your friend. She's one of my best friends and she also happens to be my neighbor. Yeah I know, it sucks but I love her. Makes me feel like a masochist. Ofcourse I'm being sarcastic, I mean who wants a friend who never talks about herself and always ends talking about different illneses. For example my friend's favorite disease topic is STD (sexual transmited disease), after she left her boyfriend and takes a test for STD, she gets the results and what do you know they are negative. But she still insists that she has an illness and that she should get tested again. Everytime she asks me if she should get tested again I always tell her no, but it backfires and here we go again with the same routine. She ends asking the same question again, it drives me through a wall, and its worse than giving birth like the Murphy Law, it feels like an upsidedown pineapple coming out from the vagina. Anyway she also gets help from a psychiatrist twice a week. By the way is your friend my friend's twin, cause it seems that way. If I were you, even though you guys sometimes end up fighting, she is still your friend, you must keep supporting her or him because nowone else will do it for them. After all she gets appointments twice a week, the pills don't take effect, its bad for her body to take so many pills, it can result to an overdose by subscription meds. This has happened and its happens everyday. So you must persevere, for this type of person its hard to change their way of dealing with life. Try again and help your friend free herself from herself.
