when I look at all the alcoholics in my family their were a lot. You'll talk to a lot of people who are addicts and they have two main reasons for using. One is to feel, and the other is not to feel. Me, im a delfinite "not to feel" You cant figure out one of the two. There are no explanations on why people turn to alcohol. Could be hiding from emotions, could be their only way to have fun, or maybe just in the genes like you say. If there was a know reason, we'd be able to catch it ahead of time right? If you feel you're at danger then dont drink. Why do you have to. Liquor is all displaced calories and sugar. Why do you want that? Mkes you fat and your gums rot. Plus you're only 18!, quite drinking!
