I am 14 and was an alcoholic for one and a half months, have i done irreparable damage to my brain and future?

I had gone through an unexplabanlly brough time in May, something very very few people and especially at this age go through so I started drinking, It felt amazing, the first few days I would steal my parents booze and maybe have a glass of whisky but then later on Id just have shots(1-3) and just wanted to feel buzzed

but I knew it was time to stop on July 31st, and I hadn't drank in 14 days it felt great, but then I had a relapse, i had a sip and it felt really warm but then a few days later I had whisky and I just dint want to stay drunk, the first few seoconds of the buzz felt great but after that i wanted it gone

and now i feel like my memory is horrible, my eyesight is like, i can't see properly but my eyes can't focus, lets say I'm watching a video on my phone, i can see it yes, but my eyes can't focus, like process the fact and concentrate with my eyes, and I feel really tired and shit

but now Im dedicated to stop, but I'm all freaked out about my mistakes and I must as because i cannot find actual shit on the internet, if i dont drink until my adulthood, am i fine? will my life return to a sober, how i felt like before i started drinking life?

PLEASE REPLY, IM REALLY SHAKEN UP
