Hi jen,
You are going through the normal struggle that takes place as you learn about what happened. I personally would not discuss this with them at this time. It is normal as you start to learn and understand what has happened, that you will question what is real and am I just making some of this up. When you say "I don't feel like these thoughts are all mine" then you are saying I doubt what is coming out. You will find this to be a very complexed and involved ordeal. Most of the time it is very hard to see the whole picture. Your whole life up to this point has been governed by the events that took place in your past.

Self doubt and denial are always symptoms of your condition. Our minds as a children have to fill in the blanks left from when the others were out. It substitutes ideas from normal life all the way up to a life that seems almost too perfect. Don't forget a child's mind will distort values and time. The dark is scarier or an hour seems like all day long. As we look at the real memories it conflicts with what we believe. This is what makes it so hard to understand.

Ask your T what he thinks would be the best time to talk to the family, but then keep in mind your T only knows what you have shown to him.

Once it starts coming out you can't turn it off, so you are correct, it isn't hiding any more. You have to be patient with this and keep an open mind.

I think it would be wrong to talk to family at this time, unless your T needs you to do it. You are not wrong at all about asking. Question everything. That is how we learn. Take care.
