I'm so jealous of everyone thats taken, I cant stand being single but i feel like ill never get a boyfriend?

basicaally, i got a bit of a reputation for myself, and most guys around my (little) town are prats anyway, i wouldn't date most of them. i find guys too immature of my own age. but anyway im so sick of being single. all of my friends are taken. its not like i can go round meeting people on my own. i hate being alone, all i want is somebody to cuddle etc, and to genuinely care about me. I feel like it'll never happen for me, most of my relationships have been like 1 month long. I miss having someone there for me,texting me and saying "i love you". i'm craving it so much, but there's nobody there for me. I don't know what I'm supposed to do, I can't go guy searching on my own, and I just feel really depressed about the whole situation.
