Anger Turned Inward

I read a psychiatric report yesterday that featured this Depression can be defined as anger turned inward. This would make sense with me because I have a real problem expressing anger (not lately, though!). I am so egotistical--and simultaneously so insecure--I get angry all the time. But I don't let it out! Instead I feel the need to project this kind, tolerant, understanding priest-like personality--which is one aspect of my character, but nowhere close to the whole man.
