Do I have a problem??

Hello! I was wondering moreorless whether my drinking habits are normal? For example, this month i have drank 7 different times (that i know, since i write it down the days i drink to keep count, but maybe i forgot some somehow), and im Pretty sure that atleast 5 of those times i blacked out. I find it that i cant just drink, i need to go all the way and black out, which gives me a nasty hangover the next day that has me going “lord why did i do that, never again”!! And then i do it again a few days after LOL

I dont drink casually or just have a beer or two, when i drink i need to get prettyy drunk and happen to grey-out, recently straight up blacking out. (Though im trying not to black out due to the hangovers, when im drunk i think differently LOL) I might even drink again today even though i just recovered from a hangover yesterday. I am also under the age of 20 (but not a minor and its perfectly okay to drink at my age where i live)
