how do u get better

im 17f and i think i might have a problem. idk if i do. i started drinking a while ago, just a beer a day to help me fall asleep. i got SAd by a friend at school and i started drinking more, started drinking whiskey and looking back it's really dumb but id fill my water bottle with 2 beers and then take bathroom breaks to take some shots.

a few weeks ago i drank what i thought was whiskey but was actually moonshine (my vovô made it and put it in a whiskey bottle) and i was in my exam and i left and started puking a lot and kind of passed out outside. i honestly don't remember what happened but i got hospitalized and yea. i havent drank since thursday

idk like im starting to think i have a problem. its kinda embarrassing what happened at school. im really lucky i didnt get in trouble for it but yea. idk what im supposed to do. my parents dont think i have a problem but im thinking about alcohol a lot of the time and when i ran out im ngl i shoplifted to get lemon extract. i dont want to spend my life like this and idk what im supposed to do
