Something's bothering me; Recently, I've been reverting back to a little kid. I see myself as kid and think like a kid. This is really embarrassing but I'm starting to play with dolls. This helps especially to cope when something bad is happening. I

Well, just to give you some background, I always felt different since I was a little kid. I never really had a real personality and I always take pieces from other people's personalities and use them. This is how I cope with emotions, communicate with people and "be normal". My personality never was stable, I would change about four times a day and when I went back to my "real" self it was flat with no distinct features, nervous and I was unable to express myself. Never mind the fact that I felt that I would mindlessly do anything someone said or suggested. Couldn't help and still continues today.
Now, especially as my mind gets worse after being beating and battered, I'm having different personalities that interrupt as I'm talking and you can hear hem by the pitch change and how the subject/opinion changes. Someone can even call on them and they will come out and talk. Also, because of my schizophrenic mental problems, I can even hear them talk in my head. I hear them and feel all the time and it makes my mind feel cloudy making it hard to stay the same. They come out with triggers and in certain situations.
Does anybody know what this is? I tried asking somebody but nobody will answer or take me seriously. Even my therapist doesn't even address it and it's nagging at me. Feedback is defiantly welcome.
