Drank a liter of vodka in one sitting the other night. Will I be okay?

I’m 21f and a new drinker and I’ve never drunk this much before. I completely blacked out for 8+ hours. Yes I realize how stupid and dangerous it was to drink this much at once. I never want to repeat this. I used a BAC calculator and it said i was at 0.55 BAC!!

I spent the next day feeling horrible like I had a fever and had a bunch of bruises. And now my abdomen and chest has been hurting. It was last friday night and I still feel off. I’m so scared I screwed up my brain and health.
