Hi Scared.
Sorry you are ill but great decision to quit drinking. I suggest that you change your thinking from "for 2-3 days at least" to setting sobriety as a long term goal, but many people find it helpful to think only for today, and then tomorrow again, and so on. Day 1's were usually terrible and very scary for me as well. Maybe see a doctor, especially given you are also sick with the flu?
Given what you said, have you considered working a 12-step program? Sounds like you might be a good candidate for it. Hang in there
