How to stop people from gossiping behind my back and get more support from colleagues?

Jojo, they gossip behinnd you because they are jealous of your success in your job. My advice isto leave gossips aside and focus on your job. You can't stop other gossips but you can choose to ignore gossips. Do what you can do to help your colleagues to do better in their jobs. If they are iron-hearted, they should feel that you are trying to help them. You don't need to explain to them because you owe nothing to them. Job is job. You are colleagues, not friends. It would be better that you can be friends with your colleagues. However, you don't need to feel down if not.
