I'd rather be taken off life support if I ever get injured and get put to a point where I might be paralysed for life
Would you not miss your life and everything in it?
Life is a fucking gamble and I don't want to be paralysed.
I hope that you never find yourself in this situation. Not everyone will agree with you, but I think it's okay to not want to live the rest of your life paralyzed. You might change you mind if it actually happened, though.
I don't want to be a burden to my family and friends.
I can understand that but your talking about what if's now. It's okay if you don't want to live a life where you are in a paralyzed state. I wouldn't even dwell on such situations now if it isn't important.
