I think some of what you're describing is recovering from addiction, which can take up to a year (or more?) from what I've read.
And some of it just sounds like being a human being.
One of the most valuable things I've begun to learn in sobriety is how to relax and stop trying to control everything all the time. To let myself have bad moods without letting them overwhelm me and drive me to hurt myself by drinking.
It's not easy at first but it gets easier and easier.
