Do you feel ugly when you see more attractive people? How to overcome this?

Hey all

I am a college student in my final year. I don't know if this happens with anybody else, but I literally feel ugly and self conscious when I see other attractive people. For some weird reason I start comparing myself to them and then feel that I pale in comparison. This often makes me feel bad.

Sometimes I feel there are so many pretty girls.. I feel literally every girl is prettier than me and wonder that I would not ever be anyone's crush. I keep having such thoughts.

Pls help :(
