What do i do????????????

ok so before you read my story, please don't judge me by the way i act or the things i do. just read it and help me out the best way you can. im 12 years old. i smoke and i drink. i dont do drugs anymore though. but i do have a serious problem with drinking. people say im an alcoholic. and i know im too young to be drinking period but i do. so dont waste yours or my time by leaving a comment that says"omg. your way too young to be doing any of that. you should be ashamed" or some shiit k?. so anyways, yeah i have a problem. last weekend, i got more drunk than i ever have and blacked out-i dont remember anything. i woke up not knowing where i was at first or how i got there. luckily i was at home. so my aunt told me the next morning that somebody dropped me off and i was wasted as hell. ok and of course there's a guy involved. he is 15. he doesnt drink, smoke or anything. he is a good guy and i really like him. but last weekend when i got really drunk i guess he had enough because he's usually the one who is taking care of me when im trashed like that. so he was really pissed at me. and ive only talked to him once since that happened and he was like "look, i really care about you but i cant keep doing this. you have a problem and you need to start doing something about it. i dont want to keep seeing you doing this to yourself. your ruining your life and you need to stop." and i know he's right. and i told him that i would try to quit and ive told him im sorry like a billion times. but he's still uppset with me. and we're not even really together. its more of a "friends with benifets" kind of thing. but we still like each other and care for one another. im the one who told him i didnt want to be together which was stupid. so we are what we are. i just don't want to loose him. i havent reallly liked a guy in so long and i knew id fall for him and then something would happen where i get my heart broken. god lifes a *****. so anyways, i think you get the idea. im an alcoholic and its getting in the way of something i really want.-him. so if you have any suggestions of what i should do about drinking or about the guy please help. i dont know what to do.
