Thanks for all of your replies!
So...I had worked three overnight shifts back to back with almost no sleep, and it resulted in my major breakdown last night. I have been struggling to cope with all my feelings (reguarding dependency) and being up for over 48 hours just sent me over the edge. I emailed him after I had got some sleep and calmed down, and he told me no worries (like always) and that he would see me on Monday.
I feel really stupid/embarassed and just plain dumb. These feelings are really hard, but they ARE worth being in therapy for.
If I ever try to quit therapy in the middle of the night...please feel free to yell at me. It's not something I would ever want, and 99% of the time I will be in some crazy triggered episode.
