Help me please. I have no will to live any longer.

First of all I'm sorry if I'm not supposed to post things like this on a2k but I really need help and Im not sure where to go.
A little background information... I'm deeply into music. I was part of a choir and intended to send a demo to a record label as well. I play, or should I say, played, the guitar, keyboard and violin.
That is until an accident a while back.
A little backstory here, my mother does drugs and I don't live with her anymore. I don't know who my father is. I live with my aunt and uncle.
A few months back I was in a car accident. It was pretty minor, so the trauma to my head and neck was a shocker and completely devastating. It caused vocal cord paralysis. My hands weren't spared either. I have only my index finger left on my dominant right hand and the other one sustained severe nerve damage.
Long and short of it is I can no longer play my music or speak, or sing.
I know I should be grateful I made it out alive. But now I need help breathing and swallowing. And doing basic everyday things. Like changing my clothes.
And I feel utterly useless without my music. It's pretty well established that I'll probably never be able to speak or sing again. My left hand may still recover but the fact is I'll never play like I used to. And I have no chance of making it as a singer. Ever. Even if I by some miracle get my voice back.
What am I supposed to do? I just can't see myself getting through life. I was on medication for depression before this anyway and I'd attempted suicide twice.
My aunt and uncle are so patient and sweet, and I can't stand being a burden on them. Before I was going to get places, make something of myself. My voice was going to take me places. Everyone said so. And now I have no voice to speak of.
In all honesty it's really just the loss of music and singing in my life that has devastated me so bad. How am I supposed to deal with this without feeling like ridding the world of myself every second?
