I also have difficulties with trust, mainly because I have trusted people before and gotten very hurt. And it probably is deeper than that as well. Still I do trust my shrink. There are times that have been rough between us and like fighting, but even though I didn't feel like I was trusting him, I was because I knew that we could work it out together so even though I was temporarily feeling mistrust, I still engaged with him, unconsciously feeling that he would come around and not hurt me or abandon me. And that was true so it fostered even more trust. Things like this though they wax and wane are just part of it when you are learning to trust someone with lots of personal meaning. There are all kinds of conscious and unconscious "tests" that are there to make sure, and make it safe for you to be able to trust. One thing I have had to learn the hard way is that trust can't be given, it has to be earned.
