you are in very serious situation ,no body can change you ,you have developed a habit of thinking bad ,and habit can’t be changed ,even people like you make situation worst for friends and relatives ,but here are some advise ,if you practice it you will certainly improve and can be happy
don’t make small things big
don’t think you will get every thing enjoy whatever you get
don’t label anybody
don’t think why i am ,think that there are many people who are in more pain than you
don’t jump into any conclusion about a man or situation
don’t give remote of your tv to others ,other can’t make you feel good or bad ,you are the creator of good or bad whatever it is
you can’t change others but you can change yourselve
don’ t expect anything even a hello or wish from any one
don’t depend on anything and anybody
enjoy where you are what you are how you are
you can’t change past
happiness is with in you not out side
and so far people are concerned do you think that if you are good than they will love you ,no ,they will not , people are selfish every one in this world love you if he thinks that it will give them something,so give love get love
try the evergreen formula of serving and sacrificing for others ,only giver are respected and prayed but don’t expect after giving
