I feel like I condone the idea I'm not good enough.

I see people I know back in my hometown. There is a boy a 17 year old guy, and he's not a great looking guy at all. I would say he's quite average at best. He had the same number of friends as I did, which is none. But still the girls in his school go crazy over him and they all like him. I saw another girl in my previous school, I was a lot of friends with. She's quite average looking I give her a 3/10 at best. All the boys in her school like her. It feels so unfair I don't know what to say. I'm a pretty good-looking guy and I still don't have any luck in the social life. I'm starting to feel like I'm condoning the idea I'm not good enough. I feel like I'm not good enough to have any good relationships. I feel like I'm not good enough to have a social life and to have any good friends. I feel like I'm not a good enough person to even exist. I don't know what to do with my life at this point. All my friends just left me for their friend groups at school, I still don't have any prospects of making any new friends.
