People hate you for 1 of 3 reasons. 1) They hate themselves 2) They want to be you 3) They see you as a threat When you love yourself you are incapable of hating anyone no matter what they've done.
Love is a learned behavior. If you don't learn how to love yourself someone will teach you how to hate yourself.
When you truly love yourself, you don't have enemies. They may hate you but you're too big to hate them back.
When you love yourself, you'll feel sorry for those that hate you instead of hating them back.
You have to get new knowledge and force yourself to really implement what you've learned. You have to set boundaries in place for yourself. The important thing is if you don't know real love, someone will teach youself hate.
