I can't explain why it happens to you, but it happened to me and I know why. I was seeing my ex-T for 4 years and never felt emotions when I was in the room with him. I tried really hard. I would watch sad youtube videos in my car before I went in, just to get my emotions going. But it never worked.

Then I switched to a new t, and I cried in her office the very first day. I cried every week in there for a couple of months.

Ex-t was intimidating to me, even though he was very kind. He was extremely good looking and dressed really well, and reminded me of the type of man who would never give me the time of day in a normal day to day life. I believe the only reason he could stand to have me in the room was because I was paying him, even though he did show me and tell me that he cared about me. It was a block I could never get past.

New t is not intimidating to me at all. But more importantly she thinks and feels like I do, so she understands me very well without me having to explain and go all reporter-y on her, like I did with ex-t. She is very attuned to me and can feel my energy, if it is sad, or happy, or whatever.

I think just being with someone who was so understanding caused my floodgates to open.

I am not saying that is what is happening for you, but maybe my experience can be helpful in some way?
