There are people who will feel threatened by the idea of you liking yourself. This is because if you like yourself, you’ll believe that you deserve to be treated well, so you won’t tolerate it when they treat you badly, and they either don’t know how to treat you properly or don’t want to treat you properly, so they know you liking yourself means that you will invariably leave them or stand up to them. When somebody wants you to be insecure or to doubt yourself, it’s because they want to use those insecurities and doubts against you. To hell with those people. They don’t care about you. They just want to be able to treat you like dirt, and they’re scared you won’t let them, so go ahead, scare them; love yourself.
