It may sound easy and unrealistic but don’t listen to people and their opinions if they’re judging you. The real friends are limited in this world as well as snakes are limited in this world, snakes will always criticize you for no reason but real ones will support you.
Start loving yourself as who you are, you’re a beautiful person who deserve to be happy and have confidence about yourself. If you are not confident, use this trick, try to talk to yourself in front of mirror while making eye contact with yourself. Moreover, surround yourself with people who truly care about you and will love you for you and not for the rank you have, hanging with the good people will make you feel better about yourself and you will care less about negatives. Apart from that, you can write down all the things you are happy with yourself and you will see you are an amazing person who’s an inspiration for many others who doesn’t have to change cause of negatives.
Strange, isn’t it? You know yourself better than anyone else. The world is filled with people who think they know you. Listen to no one else’s voice but yours.
