Hope, it seems like you have had many crises very much like this. You send an email about something and do not get an immediate response or the response you want. Then you get upset and send another email saying you're quitting therapy. Again the therapist either doesn't respond right away or it's not the response you want, and you get even more upset. Later you calm down and decide not to quit therapy after all. It sounds like it's very painful and ultimately doesn't change anything in your life.

I wonder if it would be useful to think about ways you could change this pattern? I think you could spare yourself a lot of time and pain. Not emailing is one way but I know that's a hard change to make. What if you held off from sending your emails until you feel calmer? Even just a half hour might help.

It would also be good to think (or maybe talk with your T) about what you get out of this pattern of behavior, why you keep putting yourself through all this.
