Awww freewilled, I hope you do keep your appointment!
I understand the frustration part. There are times where I feel I am just wasting my T's time, and I get so embarrassed I don't want to go back. But I push through. You should too. Its hard to find a T you like and feel comfortable with, so if you have value in your relationship work at it. the benefits are so worthwhile!
Good luck and don't give up!
