I am 18 and I think I may be an alcoholic but am not sure.

Anytime I get a bottle I drink every day. I wake up and I crave alcohol, I go to sleep and I crave alcohol. About 5 months ago I was drinking every weekend and sometimes on the weekdays I had a friend that I loved getting fucked up with, we would start drinking in the morning and drink till we went to sleep. I just blamed it on being a young adult but now I’m thinking I may have a problem. I start with 2 shots then it turns into 4 then 6 then more. Alcoholism does run in my family so I guess it wouldn’t surprise me. I suppose I’m just here to rant, not sure what I’m hoping to get from this.
