Honey, as dark as things seem right now, you have to keep hoping and believing that things will get better. And they will, as long as you keep working towards it.
You're still young, and that sometimes makes it very difficult to accomplish things, so you need to focus on what you can change and put the things you can't on hold for later. If you aren't progressing because you lack the funds, get a job. Even if you are still studying full-time or something, a part-time job gives you that regular income you need to start saving on towards your future. In the meantime, if at all possible, get your endo to put you on anti-androgens. They will buy you a year or two worth of time while you sort out the rest of your life.
As to the fears about your mom and dad - honey, ultimately you have to live for you. I know how hard it is to face the prospect of being rejected and abandoned, but until you do face that possibility, you won't advance, because other people's expectations, or rather, the expectations and reactions you think they have, will rule you. If you truly fear they will react badly and abandon you, make sure you are independent before telling them, but honey, somewhere along the line you will have to face that fear. Remember, when you try to please everybody you just end up disappointing them, yourself most of all. Be true to yourself, live your life well and the rest will follow.
As to the sex thing - honey, that's normal too. If you're anything like me and going through a later-puberty (which I've noticed is fairly common amongst us) your male hormones are now kicking into overdrive. Getting onto anti-androgens will help alot with this, not to mention blocking the T from masculinizing your body more.
