I think it might help to remember that you are going to therapy for your own benefit, to deal with your issues, and it is your thoughts and emotions that are important there. Therapists are trained to listen to stories of trauma and whatever it is, whatever they feel about it, they will handle their emotions, and you should just worry about yours.

To be really honest, I think seeking a "perfect" therapist is not a matter of being too sensitive but of finding reasons to avoid the possibly difficult and painful process of therapy. Nobody is perfect. That said, there will be therapists that fit more or less well and if one person is too loud and overbearing, maybe try another.

I was randomly matched with my therapist by my college's mental health service and it's been fine.
