Can alcohol poisoning go untreated?

So I'm a really small person who doesn't drink often, and the other night I got WAY out of control and drank almost an entire bottle of vodka, taking shots with no chasers, etc. Well I was away from home and am underage (please don't lecture me, I have learned my lesson!) so I didn't tell my parents but I started puking around 4am and didn't stop until 4pm the next day. I couldn't even keep water down. I was throwing up at least every hour. I have never felt more miserable in my life. Well today I started thinking maybe I had alcohol poisoning, and I read online that if you are still throwing up 8 - 12 hours after your last drink (which I was) that you definitely had alcohol poisoning. So my question is, if I did have it, since I feel better now does that mean it is just kinda healing itself? Or do you think I should still seek treatment for it? I really don't know what to do. That was friday and it's sunday night and I haven't thrown up today but am still nauseous in little bits off and on. What do you suggest I do?!
