I experienced a lot of anger with my partner the 1st couple years. I would go for long walks after yelling at him Sticking my head under the pillow and cursing very loud, or having a couple beers.. Over the years I use YouTube meditations daily and get counseling sessions for a while. I have also found energy work such as Reiki or Shen from a master has helped me release buried trauma, anger etc that I didn't even remember till it came up. If you are on edge a lot, you might try CBD oil as my partner has so mellowed out the last few months and it also aids his sleep.
