It is ok, I do not see at least in california a legal problems with leaving as a woman.
You would have to see a therapist and leave as a woman for 2 years
to change your license
How are these types of support groups set up, what can I expect from participating in one, and do they really help resolve any personal issues this lifestyle can cause?
Go to your local GBLT center and see if they have any groups. The groups really help my clients. It provides a social experience with others who have the same lifestyle. You will not be so issolated if you join one of those. If they do not have a group ask them if you can start one. They also have counselors that can help yu with resourses
