You said your husband is away and you feel like you're being watched. I think Lost means do you feel like you are being watched from an inside part of you, or do you think a real person outside of yourself is watching you in some way?

It is really, really hard to trust the reality of some of the memories that other parts of us bring to us. I have been there (I think most dissociative people who have experienced amnesia can relate to this) and I know how truly challenging it can be to deal with. We went through many years of therapy gradually putting things together and then came to a point where we decided none of it was real. We abandoned therapy and we abandoned our selves. And we lived a semi-happy life for a while ignoring (dissociating!) all things that challenged that position. (I also need to add here that the 'semi-happy life' involved living in a straight-jacket so as to avoid any potential triggers that could challenge the decided upon world view.)
Now, many years later, I find myself here, faced with the evidence that the inner world was a reality all along, and the inner 'demons' we found there before are still there.

But, that doesn't mean that the things remembered there are literally true. It doesn't mean they aren't, either. I - we - will never know one way or the other. But I know now that the emotional reality of the inner demons is real. The feelings, reactions and pain they feel is real, and it needs to be dealt with. It is a part of this being here, and it isn't going to go away, and it isn't going to get better on its own.
This is all my very long and roundabout way of saying that the actual truth of the memories can hardly ever be verified, but it isn't important anyway. What is of crucial importance is healing the emotional truth.
What I have learned from my own experience is that if I depend on actual verification of the validity of the memories my others bring me before I will grant myself permission to accept their inner truth, then I will never be able to heal. That verification will never happen.

(By the way, two of our abusers admitted abusing us, and that still wasn't enough for us front ones to believe the memories of being abused by them, so go figure!)
