Okay, so I know that a lot of people are insecure and my friends talk about not feeling good enough all the time, but I never felt that way..like I know I am really attractive and better than most, and I feel like most people don't even feel good. Is it normal? Is being confident wrong?

You are not better than most, you think that you are better than most, just like your friends think they are worst off than most.
I think it's normal to know your place in the hierarchy of beauty, but that does not make you "better than most" if there are people who are uglier than you.
If you really are physically attractive, then naturally you have been treated better by society since childhood. How can you be truly objective then, if you have not experienced what the rest of us have? How can you judge others for having lower self-esteem when you've had an easy ride and they haven't?
