I've been thinking about this question today. When I was having therapy with my ex T I felt terrible. I re-experienced some horrible childhood feelings. My ex-T was kind of thrilled that I was feeling my feelings. The thing is it was a repeat of my childhood, I coped with those feelings all by myself again. I think that there is a theory that it is helpful to feel those feelings, but I don't think that what happened with my T helped. With my new T I feel held, so I'm not that lonely child again. I'm not feeling so terrible, I'm actually feeling quite good at the moment. I'm starting to question whether it is necessary to feel terrible feelings to have successful therapy.
