I have a question

Ok dont bully me i was new to drinking when this happened but about a year ago me and some buddies were all drinking and we had a wild night we went to sleep at around 2 am and when i woke up at 10 am i was still blackout drunk after that day any time i wanted to drink i take a sip and i immediately feel like throwing up doesnt matter what i drink i immediately wanna throw up after a tiny sip and i still have this issue after an entire year and i wanted to ask the more experienced drinkers what caused it what does this mean and can i ever drink again
