I've never been in your situation, but I know a couple of people who are. One of them just cross-dresses & goes by another name. The other is convinced they want a sex change. Have you tried "dressing the part" to see if this is something you want to do surgically? Any kind of surgery can be a scary thought, especially one that would be so "life changing". You may want to start with something less drastic to help you figure out what you really want.
