I don't know whether it's a nervous or mental breakdown. But before I got so angry or I get too emotional, I started hitting myself and screaming. This is in the past but what is this? A nervous breakdown? I get confused to what it is. I remember another time I couldn't take it and I got so angry that I screamed (I was near a beach and it was empty) and started hitting myself with a branch. I got a bruise for that.
