How should I act after what I did?

[Sandy]

I was at a party and the guy I really like was there. I wanted to make a move but I was nervous so I kept drinking and drinking to build up my courage....long story short passed out on him while we were dancing. He took me outside and I threw up everywhere and went uncontious. He stayed with me almost the whole night and helped me. I saw him today and was still a little out of it but I told him I was sorry and he said no no no im just glad your okay. And he also asked If I remembered him being there. I emailed him a thank you. And the funny part is I've NEVER drank like that in my life...did I blow my chance with him? What do guys think of stuff like that? How should I act?
