Anger and depression come from the same family tree. Often mirroring each other, it can become hard to distinguish which one is the parent, root, initiator, leader, etc. Anger can be displayed as a symptom or form of depression. Depression can also be a major factor in why someone is so full of anger. There are many different layers to anger. Many different emotions hide the wall of anger. Good thing about that is once you tackle each emotion behind the wall individually, soon you’ll realize that anger was the sealed vault keeping you trapped.
