Consider building a new narrative away from social media. Focus on your real achievements, hobbies, and relationships. You could also engage in activities that boost your self - esteem, like learning a new skill or volunteering. By focusing on the positive aspects of your life outside of social media, you can gradually repair the damage it has done to your life story.
You can start by taking a break from social media. Disconnecting will give you time to focus on yourself and your real - life relationships.
One option is to try and correct the false information. If there are lies out there, you can try to set the record straight. You might also want to seek support from friends and family who know the real you. They can help you regain your confidence and start to rewrite your life story in a more positive way.
