Yes paranoia is super normal...so is self loathing...disgust.....FEAR of what you have done to yourself....or FEAR that you will "never care".....this really will pass in a couple more days....
You drank for a long time..you have been suffering for so long...I hope Day 4 you find something to smile about...even if it is the fact that a light bulb works in your house.....find one thing to be grateful for that you did not "see" when you were "suffering".....
I try to do that each day...find something to be grateful for cause clearly life sux for many of us...and my life sux really bad at the moment...but it would suc worse I know this...if I was drinking....
