Most definately contact your therapist. If you are worried about the texting rule, then call. Try to go in and see them.

I hope that they can still see you, or at least help you to feel less overwhelmed and hurt.

Also, when this event passes (and it will, I promise), I think it will be very important to reflect on it and try and gain some insight from it.

How could you have changed your behaviour to have better helped yourself? Did you leverage the resources available to you as best you could? How can this be avoided/minimized in the future?

All I'm saying is that this could be a great opportunity to learn about yourself and how you react to situations in a manner that may not be best for you.

We've all been there, it'll get better.
