Hi 4510,
Myself gave some great information. I just wanted to say welcome and good luck. Definitely the best thing to do is talk to your therapist. He or she might already know what's going on and if not, needs to be aware of the possibility. It's a hard thing and the brain is so complex. It's amazing what it does to cope.

My T knew what was going on with me well before I did. If you already feel safe with your T, that's a major plus I think. I hope it's not what you have (because of the major struggles involved with it) but your T will know how to help better if all the cards are on the table.

Good luck to you in your journey to healing.
