I'll just echo everyone else. Just trust little by little. Give your T some "tests" and if she passes, you know she is trustworthy, and so you can risk a little more the next time. Start with little things and build. Make yourself do something each session that helps build trust. You can even tell T this is a goal you would like to work on. Maybe she has some trust-building exercises you could do together. It would be very hard to do trauma work without the trust. ((((hugs))))
