I've always been an angry person, it affected me very negatively as a child(before high school) but i am perfectly externally adjusted now i think and people i now know would probably be very surprised if they read this about me since i have a pretty nonchalant personality on the regular. I can control my impulses very well, they only really break out when i'm on my own but usually I can placate my anger by hitting random objects like pillows, crying, and sleeping when i'm worn out from those things. Then i usually feel a bit better.

The thing i described in the op isnt the only way i get angry and frustrated, though. I generally am very sad, especially when those kinds of things in the OP get brought up. I also generally accelerate my anger, which is to say that due to those things, when I am alone minor annoyances can set me off into the aforementioned hitting and crying. I never go that far if I'm with other people but i will get more clipped/short with people if I am already frustrated from those things.
