Cece, sorry you are going through this. I recently told my therapist something I had never said out loud before either. I had to write it down and read it to him, but then I was only able to very briefly say it, and not give any details. You don't have to do it all at once. You can tell him that you have some things that need to be told, but you cant do it all right now. Then just tell one part, one thing, that you can get out.

If he is a good therapist and knows you well, he probably already knows that you are holding something back.

Just do what you can a little at a time. Speaking from experience, once you get it out of your mouth, from brain to mouth, nothing terrible happens, it hurts emotionally while it is being said, but you DO live through it.

Good luck~
