Any angels out there tonight?

I've been having probelem on top of problem lately .. and ive realized when i have a problem i drink .. only because it disappears for a short moment no worries. I used to take sleeping pills when something was wrong so i wouldnt have to think about it. My best friend gets onto me about it i say i can stop but in reality .. i dont think i can . Im 18 going on 19 in may.. a few people joke around sayin ur going to be an alcoholic... i deny it but could i truly be heading this way? ...when i drink i feel a boost of confidence like i can do things i couldnt do completely sober i feel almost invincible ..and like no one can hurt me.. help... this cant be good
