It's a daily struggle for me too. I find myself limiting my interactions with people and distracting myself with music, comedy, self-help, movies, etc.
Other people have found refuge from renewing their relationship with god or a higher power, some form of mental re-framing/re-wiring (there was a guy who posted how the Sedona method had helped him, I'm sure there are other techniques that escapes me right now but you can google it and see if it helps you), etc.
