I think that SoupDragon put it perfectly ....

"I too find it very difficult to trust. My T has spoken about how this doesnt have to be an all or nothing thing and how we may trust different people with different things. T also said it is about my own boundaries, that I can't control others, but I can control how much I am willing to risk and where I draw that line. I am not entirely sure how that works in real life but I am slowly getting my head around it.......I think."

I couldn't have put my thoughts any better as I struggle with this concept as well. My T an I had a similar conversation a little while back about this same topic.

It looks as though quite a few of us can relate
