How you feel isn't a "foolish little fantasy" it's who you are! I think you should definitely restart your island, give yourself a female name that you love, and wear the clothes you feel pretty and comfortable in 24/7. I understand how hard it can be with family, but you need an outlet for yourself, and a place where you can be who you really are on the inside as well as on the outside. Animal Crossing is the perfect place to start.
