Dear More,
I also believe that the therapeutic relationship is real. Further, that it is okay, in fact, necessary to depend on the relationship sort the way you would depend on a parent. It's a way for us to make changes, that would be too difficult otherwise. Yeah, it's scary for sure.
I think that expanding your support system is a good idea too. I know how scary it can be but try with one person at a time.
Good luck and welcome!
