Sounds like a therapy technique gone wrong. The T was probably trying to make you understand that we have to move on from the past. That said, this to me was totally wrong and not the way to handle the subject. But, it's possible you took it wrong too. I would discuss this matter with your T just one time. If you don't like the T's answer as to why he/she did that, then find another T. Before you end this discussion tell this person exactly how this made you feel. The T needs to hear it because it is not his/her job to make you feel worse.
