Sometimes being too good is also bad. Sometimes you don't even know what is the reason that they start hating you, what is the reason that they cut you off suddenly. Sometimes you're bad person or villain in their story for no reasons, though you might not done anything wrong for them. They start speaking bad for you without reasons. They start gossiping bad for you without knowing your situations. I understand you feel hurt but don't worry. You focus on what you can control. Rest, the God will see.
