I would suggest writing what you need to say and asking your T to read it. Whatever it is, your T is there to support you and she only wants what's best for you. You may not want to talk about it, but you will eventually.

Shortly after starting therapy, I told myself that if I wanted to get better I would hold nothing back. There have been times when I've had to force myself to say things. It takes a lot of energy, but in the end it is worth it.

Think of it this way, what happened is a part of your life and that part is effecting your life now.

I really encourage you to find a way to tell your T.

Good Luck
