Alcoholism Recovery & Treatment

I’m only 16 as well, but i have depression and I self-harm.
Recently this summer, every time I felt sad, irritated or upset and angry I would drink until I was drunk. When I was drinking I would get past that happy stage then if i didn’t laugh I knew i would break down crying.
Now I’m back at school, and I was really upset the other night and I just kept thinking to myself ‘I need a drink’. In the end I got some vodka from some boys. I’m not an alcoholic, its only been like 5 times, but every time I get upset/angry I just think of alcohol.
Help? I’m confused and scared. I’m already having counseling..not on medication.
