() Where do I go from here? (Please Read Details)?

The support group sounds like a great idea! You don't have to dress in a way you don't want to. I would definitely start looking into not only support groups, but people you can just be with and have fun while being yourself. Maybe a nightclub scene, or just a group of friends who are comfortable with your trans-ness, and who you are comfortable being around. Just get out into the world and be who you want to be!
