Had one when I was about 10 years old. They indeed suck the ass. I had to have my whole left big toenail removed completely (probably just like you). It was lame as hell. I had to soak my foot in epsom salt for half an hour a night and basically watch a new toenail grow outof what really looked more like an amputated nub called my big toe.
Heal that shit up and be done with it!
