To me, the mere idea of faking your death and/or running away to another place far, far away, is a dangerous fantasy, and is very, VERY selfish. For one thing, it is a ploy at removing yourself from the responsibility you have as an individual human being for your actions, and how they impact those around you. For another, if one were to actually do this, it would do far more damage to your loved ones than coming out to them would ever do. No one wants to see a loved one die/vanish. No one.
If a family member of mine were TG/TS, I would rather they came out to me so I could be supportive and loving, as a family member should. Yes, I will admit that I have dreamed of someone coming and whisking me away, but I also realized the damage this would cause to my family and friends. It is far better to come out to them, than to just write them off completely. As Julie said, you wouldn't even be giving them a chance to show you how much they care, and if they don't, well...at least you know.
Be responsible for yourself and your actions. As Ladyrider said, live your life.
