I need help

I’m 22 years old, graduated college in August. I was an extremely high functioning alcoholic in college (Edit: Since high functioning alcoholic isn’t a thing let’s just call myself an alcoholic who got really good grades). Everything got worse when I moved into my father’s house away from everyone and everything. I used to drink at night taking sips of any alcohol I could get my hands on (Back in Sept-Nov). Now it’s March, I lost my part time job and have been practicing for my career job interviews so I can move out, but I can’t help but drown my sorrows at night. I feel stuck and I want to stop drinking and feel better but I’m having such a hard time but the idea of being fully sober seems so far to me. What should I do? I’m too embarrassed to tell my parents. I just want to be sober and not feel like shit so I can put my best foot forward. I know I have so much to do and still drink when I’m done studying, and it makes me hate myself more and more everyday
