Could it be that anger is just a disguised sadness? It’s easier to be angry than to be sad. Sadness requires people to accept situations without blaming anyone, not even themselves, accept that things are just the way they are and sometimes it hurts. Sadness requires us to be vulnerable, at the receiving end of hurt, not actively repulsively angry.
Sometimes people don’t know what to do with their sadness, they channel it away to fury, hoping that after the anger, sadness will subside. Actually it looks like some people transform any kinds of negative emotions to fury.
