On the one hand, four months in trauma therapy isn't a lot of time. However, your LCM may be right--a good T will put you at ease at least in the beginning of the relationship. If there is no warmth, then attachment is hard to come by.

In my own experience, both T's have given me a "good vibe" from almost day one. I got kind of a spark of hopefulness that "hey, this might work out".

Is there another T that you can interview (or a few) so you can see if you feel a difference?
