Unfortunately, you will have to FEEL it over time. Intellectually I knew I should trust my T. but I couldn't. I have the exact same fears and have told her. And, she won't tell me not to worry about abandonment. She wants me to experience over and over things being ok.

It's really really weird but I started to trust her when she suggested spacing my sessions and possibly referring. I'm not sure why THAT would help my trust issues. Seems like it would have done the opposite. I did a ton of searching within and realized that I HAVE to trust her that she knows how to help me.

I HIGHLY suggest googling trusting someone. I wish I knew where I wrote it but it talked about trust being a choice. You have to recognize in every relationship you can get hurt. But, if it's a good relationship you will trust and be prepared to work through any hurt that might come up. So, you have to not only trust her now but trust that any other issues would be worked out. You have to CHOOSE to trust her and take a leap of faith. I hope you google and find what I read. It really helped me.
