I get very lonely at times?

thats it... im a 16 year old male, i see other teens my age going out to parties and stuff. it makes me look at me and realize i dont eally have any friends. im pretty popular, but people tell me im awkwardly quiet sometimes. I talk to people, im just a little weird. i talk about religion and aliens alot. teens arent really on that. my family sorta sees im lonely too, my brother takes me places sometimes. ive tried talking to people but somewhere i dont click. i eat out of bordem alot, dont worry though, im skinny. Advice?
