No one really faces his anger and lives with it. What we usually do is forget about it, bury it in the deep abyss of the subconscious. And yet when something silly happens, all of that anger surfaces again. Just like a volcano, its quiet and people forget it about for years and years, and suddenly when it erupts, things get ugly!
So how to deal with that much rage? Simply be aware of it! When someone tells u mean words, or does something to make u upset, be aware of your feelings, watch them, watch your anger, and suddenly when you do, you'll notice it doesn't exist anymore.
The light of awareness is a huge factor when it comes to dealing with our deep hidden feelings. Heal yourself and your wounds by living them. Your anger is like a black thick blanket over your happiness, shed some light of awareness on it, and it'll be gone.
Go back to your deepest sad issues, face them! You may cry, weep, vent! Nothing can stay hidden for long.
By this, you heal yourself, heal your psychological state, and your less tense, and more stable!
"Anger is a poison. It may hurt the others, it may not – it depends on the other – but it is going to hurt you certainly."
