Don't keep shit bottled up. I lost a friend to that......he used to say if you just pushed it down far enough it would go away. Ended up dying on the way to the hospital from a self-inflicted gunshot wound. Vent. Get it out. People say expressing emotion is a sign of weakness. That's insane. Becoming vulnerable enough to face hard shit takes more strength than most people can muster. Suppression and denial are the easy path.
