I'd like to add that it is very unusual for any mental health professional to tell to not to talk to your family. Granted if your family are definitively abusive and are known contributors to your illness, it's common to suggest avoiding the specific member of your family that is known to cause problems, but even then most are extremely cautious about ever telling a patient to limit their contacts.
And I have seen brain scans showing effects of PTSD, so while I don't have that data on hand, I believe you.
Long ago in my past I had long periods of dissociation and much like what you are describing, including occasional voices. Voices are only a real problem if they are telling you negative things about yourself or to do things you know to be wrong. Otherwise it can be just a way for your subconscious to bring your attention to your thoughts. So, what's more important than their existence is really what they are saying. To me, based on very limited information, it sounds more like you are responding to having had the full weight of trauma brought to your awareness and are trying to adjust to being atypical. That's a hard process and you deserve to be supported as you traverse it. I hope you can find someone who can give you room to explore how your mind is working so that you can get through this and start of healing the cause.
