Should you bother?
Well, if it's going to be a bother, then no. I don't think transitioning is something that can be approached half-assed or with an Eeyore-like attitude. It's hard work.
But I don't think that's what you're asking. So I'll answer the question I do think you're asking.
Yes, you should pursue this. If your life is so miserable that you feel suicide is your best option, then you have nothing to lose. There are resources out there, even in the middle of redneck right-wing land. You'd be surprised who is in the same boat as you.
So take a deep breath and calm down. You're young, you're not huge, and the hair? I'd kill for your hair! Worst case scenario, you'll wear a cute wig like many of us (and like so many cis-women do, and you'd never know it.) Time is still on your side.
You have so much going for you right now. And we'll do whatever we can to support you. But relax, read some of the stories on this site, and you'll begin to realize that you're not alone, you're not unusual, and your life is truly worth living.
The day you decide to live your life for yourself and not for anyone else will be one of your happiest.
