((((invisigirl)))) Sorry you are going through this and that you are feeling overwhelmed.

Could you try writing down what you want to say to T? Or even start by saying to T that it is difficult to say?

I wouldn't recommend stopping therapy. Sometimes the things we are running away from are what we need to face in some form. It isn't a race, and you don't need to say everything at once, but even if you could just let T know that there is something you want to say but don't know how to. That is how I started, and I still haven't told her what it is yet, but for the past few weeks we have been talking about why it is hard and what can be done to make it a little easier. I am just using my personal experience example to illustrate that your T probably won't push you to say what it is, but they might try to make you feel more comfortable and see where you are hesitating.
