well it sounds like something i'm sure many people will tell you but first you must love yourself. no one can love you if you don't love yourself (trust me been there done that). Its very emotionally trying to be with someone who is constantly down.
Tell yourself: "OK I'm blind in my left eye but so what there's plenty of people out there who are completely blind." (something along those lines)
or
"Yeah I'm not really emotional but at least I'm not cruel to people and don't start crying every 5 seconds" (or as said before something along those lines that'll make you feel less bad about those things)
A good way to meet people in general is join something at school or your community that interests you. This way you have to meet people and talk to them about something, potentially even a girl or once you make friends there they might even introduce you to their friends outside the group/club.
