I think 2fish has done a good job of pointing out how loved ones consciously or unconsciously can trap you into a no-win situation. If you go behind their back in any way, it can be considered a lie by omission and if you tell them up front, they don't want to accept, disagree, won't 'allow' you to get the help you so desperately need.
I've hidden my girl clothes, in whatever form they took at any point in my life, for over 50 years. Why? Duh! But so often loved ones either don't believe in the therapy you need or want you to avoid it so THEY won't have to accept it!
This is a turning point in your life. Whatever you do, as others have said, don't just sit there until you have bad thoughts with potentially bad results. You can't have it all. No one in any situation can have it all. There's a cost to everything - haha...even having all the money in the world has it's cost in one way or another.
I'm in the process of losing my wife, probably my kids and with that two beautiful granddaughters. I'm fortunate in many ways because I am in a better position financially, but, without going into great detail, I'll need to stretch considerably to get myself an apartment where I can keep my job and at that, I know that once I begin to transition I'll lose my job anyway. The point is that we are all (or most of us) going to have to give something up to become who we truly are.
You can describe a horrible life situation and you can feel somewhat helpless. But that is NO place to be. You fear being in a neighborhood where you might be hurt. If you stay in this feeling of helplessness, where you can't get out on your own but your parents won't allow you to do what you need to do, I'd say you're already in a neighborhood that is dangerous to you! One way or another you've GOT to escape that feeling of helplessness.
For one thing, coming to this site was good - now, turn around, bend over and let some people here give you a good swift kick to get you going! No offense, because an online TG friend of mine has been kicking my butt for a while now and it's doing me some good.
So here's a kick from me - one who needs lots of kicks herself - GET SOME HELP!!! Find a support group nearby - hopefully you can find one online. Ask on this site if there's anyone living nearby you. Get some face-to-face support.
I'm noticing here more and more something that is very important for even the neediest among us; we all need support. There are some wonderful people here who go to great lengths to reach out to others and give them help...and also are need of help themselves. No shame in that, at all. The only 'shame' is that it would be a shame if you don't get the help you need!
Good luck, but get moving!!!
Hugs,
