Things more emotionally constant for me after 3 months too.
whenever someone or something upset me in those initial days I tried to use the time out rule - I'd get up, write a post and then walk away - when I came back later if I still felt the same way, then I'd post. It was pretty rare for me to send my first draft
I also tried to use the principle of Occams Razor which is basically that the simplest explanation is the best.
I went off half-cocked several times over things or people before I internalised those principles.
