Anger is often said to be a healthy emotion. When depressed, you’ll be considered healthy once you can express anger. Anger is a therapeutic emotion, because it excites you, elevates you out of gloom. It’s the sign of LIFE.
In the opposite, sadness is the source of all diseases. If you can’t escape the abyss of sadness, you’ll be forever trapped in depression.You don’t want to eat, you don’t want to be happy, you don’t want to be better: sadness is the herald of DEATH.
HOWEVER: recent mental health literature have recorded that behind depression, there lies anger.
Anger leads to nowhere. Anger sure does fills you with pent-up energy; but it requires a release. After the release, then what? You’re left with an incurable emptiness. Think about it. You slam a door, you shouted out loud, you punched your pillow… then what? Absolutely nothing but emptiness, and a soiled feeling–a feeling that you’re dirtied by anger. You start up full of energy, and you end up hollow.
Sadness, on the other hand, does not lead to an endless tunnel. Sadness IS sad (no pun intended), but after you reach the bottom, you’d feel the need to fill the emptiness with something, anything. Unlike anger, you start out empty, and you end up longing for something.
All best-remembered works of Shakespeare are tragic: Hamlet, Othello, Romeo and Juliet, King Lear… why? Rachmaninoff’s last work is a requiem: Symphonie Pathetique… why?
All tragedy leaves you with the need for fulfillment. It leaves a gaping hole screaming to be filled. Just as you can learn from failure, so can you learn from sadness. Without sorrow, there’s no real joy. Sadness has the power to revive you.
Next time, I’ll choose to be sad rather than mad. 
One last word:
My sister is a very expressive person. You can read her by her face. Whether angry or sad, moody or excited, it’s all in obvious display on her face.
I’m not that kind of person. If you think that I’m a nice person because you’ve never seen me angry, then you don’t know the real me at all. If you think that my life is perfect because you’ve never heard me complain, then you don’t know the real me at all. My ‘monster’ shows up only in front of people and friends whom I truly care for. In a sense, my Ms. Hyde is a very shy persona. She’s manipulative and smart: she knows that only certain people can accept her–only those who are so close to me they can never distance themselves away from me. (Hmm… very Edgar Allan Poe-ish)
The Japanese say, a man has three faces. One face he shows in public, one face he shows to friends and family and one face he only shows himself.
I choose to be happy
I always remember what Yoda said at the first saga of Star Wars Movie when talking about anger. He said to Anakin Skywalker like this:
…fear is the path to the darkside
fear leads to anger
anger leads to hate
hate leads to suffering…
Those words hit me in the first place. Suddenly, I’m getting more understand about what is going on.
That’s why Anakin had become a Darth Vader, because he always in fear…
That’s why the evil had failed to tempt Jesus at top of the hill, because He never be afraid
There are really no bad emotions. There are only bad ways of expressing or handeling them. Anger, sadness, joy, love, hate. All have their place. Depression happens when the normal flow of emotions is blocked or diverted.
Being of an Italian background I know how to let emotions out. Being 43 and disabled I know when it’s worth letting the emotions flow and when it’s just a waste (I only have so much energy to expend now that I can’t afford to waste it on nonessentials).
As Budi said, coose to be happy. Most people don’t know it but we can all have control over our emotions. But since few people know this fact they end up being lead by them.
When the world kicks you in the teeth it’s ok to be unhappy or angry or frustrated (or all three) but you should not spend to much time on them. Move on to happy, or at least mildly amused. You’ll live longer.
