I was diagnosed with bipolar disorder a few years ago and firmly believe it to be incorrect. A therapist I had before the diagnosis thought it was DID and I think she is correct. I can say that I seem to have an "inner child" that appears to get stuck. One minute I'm ok, the next without warning I'm a teenager again. I have five kids and I look at them thinking who are you? I recall feelings of not knowing who these people are (my husband, my kids), feeling rage, sticking two fingers up at the world etc I become terrified that I am supposed to be a mother, I'm meant to be 30 years old and I think how am I supposed to look after you when I'm a kid myself. I don't recognise my face, it looks so much older and it's not me.
I will go blank, into my own world which has been something I've done for many many years. I can't explain it well because to myself now, that's all it is - blank. Then I'm back in the room again wondering what on earth has gone on. How much time has gone by? Who have I upset this time? My husband tells me things I've said but I can only recall intense anger.
That's the teen personality. There are a few other parts I've become aware of over the last couple of years. I don't see them as separate people, I see them as different parts of the same person, some I have been, some that have been created either from other people or by myself as a means to protect myself. There's only one that has a name as far as I am aware, I don't know where it came from or why.
I think you should speak to someone better trained to help you other than your GP. As far as I'm aware DID isn't treatable with meds, but therapy. I think you can treat certain symptoms, for example anxiety if that's one, with meds but there isn't a medication to treat it as a whole like perhaps you might treat depression with antidepressants.
