Sounds like you and your therapist are doing well. You have identified the problem, what you want to work with; that is the first step. Nothing is going to happen all-at-once, you aren't suddenly going to open up or start crying on demand, etc.

You don't have to force yourself to receive help, you are receiving help! You go to therapy and are working with your therapist, you are coming here and asking for help, you are quite willing or you would not be pursuing it this hard yet!
