Welcome to Susan's.

There's a lot of good information and good people here. Each of our stories is unique but we have a lot in common. Settle in, pull up a keyboard, and explore.
Be sure to look under the Announcements heading. There you will find the rules we live by in this little world of ours: "Site Terms of Service and Rules to Live By", "Standard Terms and Definitions", and "Post Ranks". Look through the other stuff there, too, like "Age and the Forums".
As LordKAT said, transition is not an all-or-nothing proposition - there are many stops along the way. And as he said, it is usually very helpful to have someone you can talk to who is non-judgemental and trained to listen to what you are saying and not saying - a therapist.
You might also look for support groups in your area. Many places have them. Some are helpful and some aren't, but it can be really useful to listen to others' experiences.
Happy exploring and good luck.
