NB- I see that we're both the same age and relatively new here. I know EXACTLY what you're going through right now. I started therapy a month ago. I was lucky, my therapist is a dream. He's dealt with JW's before and knew a lot about them.
I know what you're saying when you talk about the apprehension with the first visit. I don't mind discussing my past, as painful as it is. Its actually dealing with and getting over issues that made me nervous. It much easier to let the bones stay buried, know what I mean?
Good luck, I hope your therapist is a good one. If you want to chat with me about anything, just PM me. I'd love to hear from you.
