Do it. Just do it. Seriously, if I had a job I would be transitioning right now with my own money. I don't think my parents would ever accept me and I am not very connected to them which hurts a lot, they really have no idea of who I am. I came out to my mom and she now pretends it isn't an issue. Like me liking men as well. But be sure you have the support you need from friends, or just join a LGBT group, when you start. You won't survive transition alone, or being LGBT alone for that matter. Oh, and if everything turns against or it gets really ugly which I really hope it doesn't, be sure you have somewhere to go. I sincerely hope it doesn't happen but you can't afford the risk.
