People with low self-esteem are more likely to criticize others. That’s a FACT!
So whenever someone is saying something bad about you, gossiping about you behind your back…just feel sorry for him/her and keep doing your thing. DON’T worry about it. Most times they’re criticizing you out of jealousy and if they’re jealous it means you’re doing better than them and just keep it that way! Focus on your way and keep going no matter what people say
