Do I have mental illness?

[Matthew]

I do this thing where I change my personalities. The transformation is so scary that I feel completely different. I would call it hiding my true feelings but the feel is completely different too! The scary thing is that I can control it! I'm starting to think my feelings and thoughts are all made up in my head, hence the effortless change of heart. But others think I'm crazy. Is there a name for this disorder? Can it be fixed? Thanks in advance =(
