As a dude shorter than most dudes dooming about being short, I really recommend adopting women's approach: find the things you like about yourself and emphasize them. The things you don't like, seek change or make peace. Other people respond to your assurance, regardless.
You see a lot of men dooming about being short online. I get it. It seems like it really fucking sucks. But why aren't there more women dooming online about their respective negative traits? It's even worse for them, men care more about physical appearance than women.
