Real serious issues. I'll love everyone who answers.?

Well I am a male and I hate my life. Everybody seems to have a girlfriend besides me and I really want one. I wouldn't say I'm ugly, just not attractive at all. Recently, I got turned down by a stunningly beautiful girl and all my closest friends have rejected me. I have only ever had one girlfriend and we never did anythink and barely spoke. I have to have some helpful advise pronto because I have to sort my life out!
