I can relate to this so much. I used to get so mad about everything, regardless of how much/little it affected my life. And to be honest even with therapy, I still get very angry. It's just that the antidepressants have lengthened my fuse a bit. I have a similar issue where I cry when I'm enraged. I also live with family so I can't exactly vent anger privately. While I write in a personal journal, it doesn't really work for controlling anger. So yeah, unfortunately I haven't got solutions or suggestions, but I empathize.
