Multiple personalities appear when people can't psychologically deal with a situation they're in. It's almost impossible for me to count how many accounts in this forum is connected to a single person. The only thing I can see is a single trademark keyword used by all these accounts that makes me suspicious.

I hope the person dealing with these multiple personalities get professional help. It is not healthy and it will destroy the mind if you can't express yourself in your true form and have to resort to multiple personalities to express fragments of your own mind.

I'm not a professional psychologist, I can't be of help in this issue. I feel sorry for your situation (not the hospital ER stories but your actual situation). Some people can't cure their mental health issues, therefore they need to join a community that can give them mental health support to keep them away from suicidal thoughts.

I wish you can work on letting go of your grudges one day. It's the best thing you can do to reduce your mania, a forum like this doesn't help because people will post judgemental comments that might hurt you more.
