Feeling of unhappiness

A feeling of unhappiness or jealousy, it sound really dramatic but i believe that nowadays it have seem to be usual, not because we are evil but we doubt the tune of our ability, to be assure i will add that we compare our self with those who have been blessed with fortunes, fortune of someone which might look so luxurious from outside, which remind me of a line " everyone can see that how successful i have become but none can see my feet's abscess ".

So if i measure myself with some who is in good status then me, i will feel depressed and unhappy which can change it to jealousy but i if do it other-way around in a good sense, it will lend me a hand to feel gratitude. 

I feel sure each one experienced these feelings but as i always say we are not white or black, we are gray.

White as in all time positive, happy, grateful, soft-spoken.

 Black as in all time negative, sad, ungrateful, harsh.

Gray as in we are kind of in between which inferior in stage of mind where in all occasions we remind our self that i might be in good circumstances than someone who is not able to walk, speak or sightless, this kind of compare is healthy, it educate us in great amount and lead us to being grateful and so on to from feeling of unhappiness to HAPPY.
