sweepy that's great you wrote to your T. That was very brave of you. My T was older so I don't know how I would feel if my T was younger.
I can understand your fear of being attached. My mom rejected me growing up and I could never go to her for comfort. The one time I did ask for her comfort (I felt like she might hug me) she pushed me away. It was very hard to open up to T but when I allowed myself to she didn't push me away. Sure she could never really be my mom but with healthy boundaries, direction and guidance I was able to make big changes in my life and become a more secure happy person. It's not easy but it's worth it. Sending you a million hugs.
