Am i losing my toenail?

On December 1st I was messing around at a park with some people and a football. I kicked the football and instantly felt pain in my big toe. Only around the nail though. I assumed I pushed my toenail backwards when I kicked the ball.. It hurt like a s.o.b for a few days. The nail has turned a bruised color and feels kinda numb. I can finally wear socks and walk normally now.. But I've noticed at the very bottom of my nail, right under the cuticle, my nail is completely loose.. I can push it up and down.. But the rest of my nail isn't loose at all..

Is this the beginning of losing it?

If so, what can I expect to happen?

If I lose it will I still be able to wear socks and shoes? I've heard people tell me the toe is pretty sensitive after losing a nail..
