I was seeing a therapist for about seven years. Mostly for depression.
The first session is filled with a lot of preliminary stuff. Laying down the ground rules, filling out forms, this is why I want to be treated statements, and for the therapist this is what I treat statements. Don't expect many tears. They come later.
Ask for credentials. Look at the diplomas. Do they have any experience with GID?
If you like them & they like you can plan a second session.
The therapist will help you decide what you want to do. He or she should help you sort through all your feelings. You are going to experience some tears as you go through the discovery process. The emotions can get intense. But you'll find out things about your self that you didn't know. In the end, you'll feel much better. You can come up with a plan for your future and have no doubts that its the right plan for you.
In my opinion, if the therapist tells you to do something unrelated to helping you discover yourself then its time to boogie. For instance: "get a divorce", "get GRS", "start/stop going full time". Those are all your decisions. Instead, they should ask how you feel about GRS/divorce/full time/whatever and let you come to your own decision.
