Moon, all the feelings you are dealing with in your therapy are intense and profoundly scary. I am a lot older than you and I find them absolutely overwhelming at times. First wonderful beyond words and then terrible beyond words. I seriously figured I was going nuts untill I did some reading and also found this website and realized that the reason therapy was so damn grueling for me was because it was working! That is all my issues were being played out within the context of my relationship with T. I have since come to believe that therapy is the therapeutic relationship and wow, what a relationship! I do not think all patients get really really close to their T's but some do. It means the match between T and patient is good and it is working the way it ideally should. The best thing to do is to keep talking to your T ... as openly and honestly as you can bear.
Best of luck!
