I notice a majority of these posts dealing with wanting a date. I feel lonely is being thrown around pretty loosely. Now before I sound like Im downing you all, Im not. As stated the cure doesnt have to be finding a true love or something.
Do you have interests? hobbies? skills? go explore them. there's a group for everything. seems like a good place to find a match. if not at least someone to talk to. right?
Family? friends? need someone to talk to? they should work.
In the event none of this would help (because you lack all things mentioned) feel free to write. After which I will talk of my own loneliness (trust me, its rich).
