Hey,
I really struggle with this too. I may have had an awful week and during it I am just dying to talk with my therapist and have her there with me. Then I walk into therapy and feel numb, go blank and even though I may be telling her what happened or how I felt, I cant really connect with how bad it felt so it comes out in a flat monotone voice. Sometimes i cant even say the words and I spend a lot of the session in silence, telling myself in my head to "just speak!!!!" but i cant.

I think it's a mixture of maybe self protection - where your mind knows thinking about it will hurt so you numb it out, maybe a level of calmness of being with your therapist and feeling safe so you cant remember how it felt to feel the badway you felt, or maybe fear that by saying it, it wont help. It could be emotional exhaustion too maybe. Maybe we struggle so hard to get ourself through the bad times and waiting on our therapy day to come around that when it does we just feel emotionally spent.

*huge hugs* I can totally relate!
