The truth is people do love you. I also don't believe when people tell me that but I also know that the impulse that makes you feel worthless is not genuine. Nobody is born happy. We have to make ourself happy. Do you try to find out means to cheer you up? Even if nobody cares, you have to live for yourself. You don't need other people for your survival. Try to believe it and you'll feel the difference. Wish you well...
