You are incredibly brave for going to therapy at all. I don't think your T would blame you or get angry with you for avoiding a session; facing emotions head-on with another person is an incredibly frightening thing to do. Many people quit after the first session, and it's so easy to just walk away. I'm sure we have all thought many times about canceling an appointment. I think your T will just be happy that you are coming back and continuing to work with him or her.
