Do not tolerate being vilified. Distance yourself from those who seek to take underhanded jabs at you while maintaining their innocence. Such behavior barks of immaturity and a complete disregard for the feelings of others.
You might think being alone makes you lonely, but that’s not entirely true. Being surrounded by the wrong people is the loneliest place in the world. Before you diagnose yourself as an unhappy person, first be sure that you are not simply surrounded by negative people constantly trying to bring you down to their level.
