enfin, the crazy spinny brain is going to relax and be less bothersome with some sober time. All the manic energy and worry and fear is going to go away. You are in healing mode. You are recovering from a serious illness and your brain and nervous system is not well yet.
Give it time, understand that this is a fragile time, and don't push too much - just concentrate on not picking up a drink, healthy food, sleep, water, self-care right now.
Well done! You can do this.
