How can I take photos with people without worrying about my face

Ever since kindergarden, I have been insecure about my looks. I vividly remember not being comfortable with my appearance, but I was a child and at the time and wasn't super embarrassed. As I grew older I began to avoid mirrors and despise photos. I wouldn't tell anyone about things like crushes because I felt like they would immediately think about how an ugly guy like me has no chance with anyone. Whenever someone brought up looks, I would be as silent as possible. If someone walked by me laughing I would instantly assume they were mocking my appearance.
Now, I am still very insecure about my face, despite the fact that I don't personally think I am a very ugly guy. Whenever someone takes a photo with me all I see are flaws in my face.
I've seen subhumans that are able to take selfies of themselves and post them online while I can't even bear to keep an image of my face in my camera roll.
So does anyone have any advice on how to be more comfortable with taking photos?
