I find therapy very helpful but I still get nervous sometimes and I am never an open book. It takes me a while to get things out. I found a therapist who was able to earn my trust quickly and who doesn't judge me or anything. If you can find a good therapist who is patient, kind, and compassionate, you will probably find your anxiety lessen each time you see him or her. Therapy is not for everyone but I think since you came here for advice it shows you are at least willing to talk about what is going on so maybe trying therapy again wouldn't be a bad idea.
