You don't have to drink daily to be an alcohol. Many people drink just on days off or the weekends. I thought your living situation does not allow alcohol ? What happens if you get caught ? If I remember correctly your under 21 so , your having someone buy it for you?

I'm sorry that you can't "see" whats happening to you, you are young and have a whole life ahead of you.. I hope you get help in some form of fashion before it's to late .

Take care .
