Sometimes walking away has nothing to do with weakness, and everything to do with strength. We walk away not because we want others to realize our worth and value, but because we finally realize our own.
Then, Life is too expensive as it only instills pain, grief, regret and fear of losing others and of losing one's own life despite the negativity it inflicts. Someone once said, The only thing better than life is no life at all... That person was Buddha. I am not saying life is bad, but it does teach much negativity, so as I learn to not fear my own death as much since it is inevitable no matter how I feel about it. I have experienced and continue to experience Life, but look to peace after.
