a great start to 2009!

Here in france, I'm learning lots of important life lessons, for instance, never ever ever drink vodka.. I spent my new years puking my guts out. It was so terrible I shouldn't have gone, I didn't even feel like going in the first place, but I've been wanting to make friends so badly so I went anyways. I only had 1 glass of vodka and one glass of something else made from apples and thats all. Infact I didn't even finish the vodka, I spilled it! Then the next thing I knew, my friends were pulling back my hair and I was puking, I'm serious it went on for like 2 hours. I have never felt so sick in my life, I couldn't even stand up- I couldn't even sit up! My friends were really nice to me, they really took care of me, so that was good but I feel really embarrassed. We all slept in the basement and it was amazingly cold so I slept horribly, then this morning I didn't feel any better, I was the first one to leave. I walked home because it was in the same neighborhood. When I got home no body was awake yet thankfully, because I smelled like vomit and cigarrete smoke =[. I took a shower and then decided to take a bath and then I just sat there in the tub forever. After I got out I threw my cloths in the washer and went to bed. What a crappy new year, I didn't even notice when it turned midnight, I was puking by then..
I miss everything about home, but its worse because yes, I have friends here, but we just don't have anything in common. What am I supposed to do?!
But things with my family are great, christmas was good, we've been doing a lot of fun things-visiting all the tourist stuff in the area and the other day we went to Monaco! We might spend the day in Italy friday, if not we'll go eventually, they said.
I'm just really stressed out because I miss home and I don't have any good friends and I'm completely crazy when it comes to whether my host family likes me or not. They DO like me, I know. But sometimes the smallest thing sets me off and I spend days thinking they hate me and I've ruined it, all because of something small that actually didn't mean anything and I realize that later of course. And now this stupid party. I should have stayed home, my host family was having friends over. But I was invited to the party before they invited their friends, so I went to the party. But I felt kind of bad about it before hand and I wasn't sure what to do.WHAT WAS I THINKING! I don't think I'll ever go to a party again, I'm serious, I never like them, and at the moment, just the thought of alcohol makes me feel like I'm going to puke again. I was barely able to eat something for breakfest, I just had a piece toast and a slice of cheese( and yes its normal to eat cheese whenever here, my host family eats it all the time because theres a gazillion special cheeses in france)It was an effort to eat breakfest. Before hand I drank like half a gallon of cold water (before my host family woke up, it seemed to help.
I'm too afraid to lie to my host family so I just told them the truth, their not like my real family who would TOTALLY freak out if they knew.
So yah, I'm embarrased and upset and sick, and my hair still smells even though I washed it really well.
