Open Question: stubbed toenail falling off?

half an hour ago i stubbed my toe on the cement stairs outside my house. half of the toenail came off, i think. I cant really tell because there is skin over a part of it and it just looks really weird, Ive stubbed my toe before a few years ago and the entire nail fell off(this was a different nail tho). now this one is still beeding a tiny bit but hurts sooo much and i dont know what to do....the rest of the nail still attached is kinda loose but not enough to pull it off. and there is a lot of loose skin around
