I feel if i died right now, no one would know for days/weeks, nor care?

Other than work, they might call if i don't rock up. But I don't have anyone close enough to me to notice if i was gone for a day, or two, or three.. or a few weeks? I find myself laying in bed missing having a love, someone who loves me as much as I love him. Someone who would notice my disappearance, who wouldn't dream of losing me. I feel like i should just wish to pass away in my sleep. Can one die of loneliness?
