Yes...oh god yes. I used to cry (when I was employed) and we switched projects at work...I couldn't deal with feeling disoriented and confused and overwhelmed.
Your Ts reasoning sounds good to me. In all my years of T no one ever really explained it like that (so I think I appreciate your T).
Its also sounds like you are dealing with lots of little uncomfortable things that just remind you of the bigger change that took place, and those always hurt, too.
