Hibbsey, I am a good bit older than you but really developed severe issues later in life. When I was younger I always drank until there was no more or I passed out. I should have seen the problem then but didn't because so many friends did the same. I later discovered pot and smoked every day for some years. That cut down the drinking because it did not take as much time and no hangovers.
During the years I was raising my kids, I rarely drank and did not use drugs at all. It was when they left home I started back with a vengeance. I have realized now I am not a person who can moderate drugs or alcohol. If I use, I will use a lot and cause problems.
You have gained a lot of wisdom at a young age. Spend as much time with folks who are recovering, either on line or at meetings. They know what you are going through and can help with advice and accountability.
