1st rule of being ugly: Every ugly person has at least 1 really good picture that hides all of their flaws or is easily photoshoppable to hide flaws. Use any combination of lighting, shadows, cropping, facial hair to get this effect.
2nd rule: Find that picture and use it for everything.
3rd rule: People will be confused when they see you in real life and realize you look different from your picture. They will be disappointed. So you have to work really hard to try to match whatever level of attractiveness you have in your picture. If you're a guy and you've never put on makeup, you may need to learn.
If you think this level or worrying is too much and obsessive, I'd like to ask you this. If the way people treat you changes depending on how you look when you leave the house, you too would "worry about it".
Again, I'm not devastated that I'm ugly. I'm devastated that people treat me differently because I'm ugly. Especially after all the "everyone's beautiful in their own way" rhetoric I've heard my whole life. There's lots of people who are super successful, rich, and happy with families and they're ugly. What angers me is being treated differently because of something that I cannot control.
