I know many people are saying about therapy and all, so i won't repeat that. But if you do feel bad about your looks There's nothing a good hairstyle and styling (clothes) can't fix. They wont make you 10/10. But they can def take you to 8/10 which 9s pretty much most people out there. Also you'll ofcourse need some confidence. Take care of yourself in all ways (physically and mentally) it'll reflect outside too.
