If you have three personality and you want to get rid of it so what do you do and its not your consion?
Many people have so-called "splinter" personalities. The trick
in a case like this is, first understand that you can't get rid of
them by trying to "get rid of them." They are not separate beings.
The key is to re-integrate them into yourself. Rather than push
them away, embrace them, love them, and understand them as a part
of you. Only then will you start to re-assemble your shattered
self. While I do not have any kind of medical degree, I lived with
someone who had a thousand different sub-personalities who would
"take over" at certain times. I led him through this process, and
the splits, splinters, what have you, all re-integrated within a
two-month period.
People who suffer from psychological problems require
expert/qualified advice from competent and authorized
psychologists.
They should never take advise from incompetent individuals like
witch-doctors and religious neophytes.
