I can relate so much to it. I've felt the same thing and didn't know what was it but now that you've put it in words I understand. The therapy just reveals that side of ourselves because in the end that's what therapy is all about, you don't go there to discuss literature or math problems (although if you love your T a lot, you feel you could ask anything even math questions ) . And then when therapy ends you just wished you got back yourself together again, your previous self and discover it's quite hard to do it. In this respect I think the end, the last sessions are very important. Sometimes therapy is like a surgery, you open the body in order to reach to the wound and heal it but after treating and curing it you have to stitch it back well, otherwise can be dangerous. Before you leave therapy you should make sure you feel good enough, together enough, with all the wounds, be it completely or partially cured, closed. Otherwise you'll feel the need to talk to the T again and again, the door will be closed and you'll find yourself in turmoil. Learned it through my own experience
