The world does not owe you a thing.
People constantly complain about the situation they are in. They have no money, no job, no friends, no boyfriend/girlfriend, nothing makes them happy. YOUR decisions are what put you in that situation. YOU are where YOU are in life today because of the choices YOU made yesterday, nobody did this TO you. Stop blaming others for your misery.
Stop thinking that everyone owes you something. If people choose to help you, be grateful. Don’t take advantage of them, don’t ask for more than they are willing or able to give and don’t treat them badly after they’ve given.
If you are truly unhappy, do something to change your current situation. There are ways.
If you are just complaining to complain or gain sympathy from people, rather than find a solution to the problem… SUCK IT UP, BUTTERCUP! because you are going to be miserable for a long time.
