alcohol

hey, im 16 and get drunk roughly once a month. i want to go to college and make good money and have a good life. will this deter or stop me from reaching my goals? will i have any serious problems from doing this? i dont like to drink by myself, only when with friends. i dont think im addicted, but im not totally positively sure. i cant ask my parents or any adult or else i will get in trouble (obviously lol). can someone explain truthfully please? i would really appreciate it.
