Kerria, the honesty in your post really touched me. I can definitely relate & understand. My dad used to think I had demons too 'cos I acted moody. People view mental illness as being possessed. How ignorant! I have a hard time w/ my name as well. My birth name is different from what "I" go by. 'cos the original personality "died" (integrated). So people keep calling me 'her' name. That's a little different than your situation.
I was fortunate to have a pact w/ my people. No one was to know they were out. Sure, people saw that I was strangely moody, cheerful one minute, biting your head off the next, but nobody thought of DID, they just thought I was a ******. So my people weren't as extravagent where real people would question their existence. Even my husband doesn't know how often 'they' are out. I tell him look at the eyes, my eyes get a glazed look when I'm not out. We had gotten in a fight awhile back. I had said something 'bout his mom (who I love). I told him, If it doesn't sound like me, act like me, then it's not "me". He understood that "I" wasn't the one downing his mom. I have support from him as well as my parents. I'm very fortunate that way.
I really hope you can find some good support here. We care 'bout you & we believe you.
Love,
RhysMadison
