Hiya Shezbut.
I read your story. There are a lot of different aspects to being dissociative. The best person to talk to us your P'doc. Each person here is some where along the line of severity.
Yes it is scary when we see ourselves from above, or when our body goes off on its own tangent. Or different voices come out and you feel shoved to the back. I find it helpful to write things out in a journal to get them out of my head.
You also have epilepsy and I have no idea how that would impact on ddnos.
Please feel free to talk here. You are not alone.
