another question

im an alcoholic and im only 19, ive been kicked out of my home and sent to a mental hospital for drinking. i was only 13 with undiagnosed bpd when my mother would give me a glass of wine to get over my issues (not to mention shes also an alcoholic and so is her whole family, its very much a genetic issue) . i started drinking more heavy when i was 16 and when i was 17 i would get blackout drunk multiple times a week. i know this isnt good for me and i want to quit but i dont know how. is there anyway to develop a healthier relationship with alcohol so i dont abuse it everytime i drink? or does anyone have advice for quitting, life feels so dull and boring without it. usually weed is the only thing that keeps me from drinking because it gives me some sort of non sober feeling, but i am tired of depending on substances to feel okay
