Maybe it’s your attitude then. If you are claiming that people you call friends are only singling you out because of your physical appearance and not your personality or the way you carry yourself, because confidence is more attractive than physical attributes. you can be attractive but an ass hole and people wouldn’t want to invite them because of how they act, not their appearance
I do think physical appearance plays a role in first impressions. Unfortunate, but it’s not productive to deny it. Pretty privilege is real. I won’t sit here and say “nooo ur beautiful” because I don’t think you’d be making this post if you were conventionally attractive (if such a thing exists), unless your confidence is just extra extra low. But if you give people opportunities to get to know you, and they still exclude you because of your appearance, then they’re shallow. And bad friends.
Now, how do you know if they’re excluding you because of your appearance vs your personality? That’s tough. But this is where confidence comes in, because if you’re spending all your time worrying about your looks, you’re not giving people a chance to know you for your personality.
Again, #1 is right that putting yourself down all the time can be a deterrent. But it’s a delicate thing, because we are all insecure to some degree, and self-deprecating humor is a very common way to cope with that. Some of my friends are extremely self-deprecating, which I find funny and endearing, but others might have a different tolerance level.
