I'm just so desperately lonely and every work shift I go to I'm so happy the kids come up and hug me when they first see me.
That's sweet of them. What pleases you about what they always do?
It doesn't matter because you don't know how it feels to be so lonely.
It's a good thing that they love you and you are happy with each other. You're not lonely if you've got them.
My loneliness is so deep that no one can cure me. I take my loneliness to the graveyard.
That doesn't have to happen, you have lots of children around you that love you! Don't you think they'd be sad that you think their presence won't help you? Why not try hanging out around them more, you don't know how much joy they can bring you.
