I find that the times I want to quit or cancel T are the times when I need to be in T. It's excruciating to work up the courage to speak up and say exactly what I've been going through...but ultimately, T is there to help me work through it and I generally leave feeling so much better that I went, instead of holding onto those feelings for another week. Also, while it's fresh (and painful), is the best time to access the stuff that's needed to work through it.
