You can't change everyone. Some people will treat you badly and there's nothing you can do to change it other than to remove yourself from that situation. Not everyone is going to be kind. Not everyone has a heart like you. Some people have been taught more about hurting others rather than healing them and instead of taking this as a burden on your part—let it go. It's not on you to teach everyone to be compassionate and kind. But it is your responsibility to detach yourself from those who can't respect you or treat you well. You can't change everyone, but you can certainly change the people that you surround yourself with and give value to.
