Passed out last night from drinking – what do i do?

Drank a lot of vodka I’m also 18 and I passed out on the streets and an ambulance took me to the hospital, around 7am.

At the hospital, I woke up at 11am., very hungover and confused and the doctor took me to some place but I just left without saying a word and now I’m home and my poop is a bit red and I feel like vomiting, I’m not keen on going back to the hospital. I did a lot of stuff I regret last night and I am going to stop drinking for a few months.

Will I be okay? Any tips
