Be gentle with yourself. Do the kind of care you would do for a friend who was feeling like that: maybe a bath with some epsom salts, maybe some ice cream, maybe some rom-com movies; be gentle and caring with yourself for the moment.
Every hour, every day you don’t drink is a win.
When you wake up tomorrow check out the schedule of online meetings for the day. There’s a list of online meeting options here: Online meeting resources - browse the list and look for a meeting you can join. When you get there, you can just listen. Most meetings are free. It’s helpful to not be alone, to have some other people who understand.
Take care and stay connected. You belong, and you are not alone, and you don’t have to be alone.
