Hi Kafka & welcome!
You are not too young to realize you may have an issue with alcohol. I'm 32 but I go to young people's AA meeting once a week & I've met some neat teenagers - like 15/16/17 years old that are sober & even have time (years) to show for it. Its a little strange to sit in a meeting with kids that are only a couple years older than my oldest son, but I definitely learn alot from them
