It is astonishing that we can go through such an array of different and conflicting emotions in a short period of time, yet we are still able to function. We can still write, eat, wash the dishes and work.
Whilst inside the feelings rage and fight against one another, with your conscious mind trying to quiet the inner struggle.
We really are amazing but complex creatures. This brain of ours that differentiates us from all other life on the planet really is very complicated. Yet it still allows us to live to work through our problems. No one's problems are the same (they may be similar, but they all stem from different circumstances and experiences) but your own are the most important ones. Oh there may be wars and hunger and people dying horribly which of course it is the utmost horrific expression of suffering. But for us, our problems are the worst, yet we feel guilty for this, because of those other people that have had it so much harder than us. But does that makes our problems go away? Does that makes not cry? Does that stop us from feeling? And hurting?
It really doesn't. We just have to be open-minded and non-judgmental about other peoples (friends and relatives) problems and their own demons because for them, as it is for us, they are the biggest thing in the world.
That comprehension and compassion is unfortunately so sorely lacking in this modern world of ours. But, as we evolved in the past, maybe we will evolve some day to a stage where everyone is willing to listen to others and has no desire to cause hurt.
