irritability is common when coming off the meds. Depending on the meds, and on doctors approval, if taking a stimulant you skip one day a week so you dont built up resistance. The day i choose is when i not normally around people or at least forced to deal with them and i just focus on enjoyable things to get me through it.
Edit: stop watching "all" news. Its only negative to a positive life you want. I selectively only subscribe to tech news so i still learn new stuff happening but only stuff I enjoy.
Accept the fact you will always have many unfinished projects, which is ok to have, and when you finish a task or full project always celebrate to help teach your brain that it will be rewarded for completing things.
