You've said several times that you can't take it. Well, you got through the day, and your pain didn't kill you. That much pain with no further reassurance from your T, and you are still alive and kicking. Maybe this will help you to trust your ability to endure extremely negative feelings and deep pain. Hell, you even went to work.

Suffering isn't fun. That's why it's suffering. I have found that when I am in incredible emotional pain, it only increases the pain to tell myself I can't take it. Some irrational mortality fear kicks in. On the other hand, if I can tell myself that it sucks horribly but I've made it through worse and that however I'm feeling will definitely pass, the panic doesn't rise the same way. The pain doesn't snowball on its own.

Quite a lot of suffering has resulted from therapy, but, honestly, pain is my best teacher, so I'm far less avoidant than I used to be. And I know that a therapist who shields me from pain that can teach, isn't worth his or her salt. So, do what you can to make certain this crisis isn't wasted. Learn everything you can possibly glean about yourself from it, and give serious thought to how you can handle these circumstances the next time they arise.
