Self-love is honestly what it sounds like. It is an unnarissistic way of caring and loving for yourself. Everyone should try it out because it is okay to take time for yourself. Not only is it treating yourself right mentally but also physically. Forgive yourself when you make a mistake, love your "impurities", and seek to make yourself happy. As Christians we should practice this because God made us in His image, therefore we want to keep his image by maintaining self-love and love for Him. Feel free to ask any questions you might have.
