My heart is a lonely hunter

There is a sadness in my heart that has yet to be explained to my mind. I can't seem to identify what is going on within. There seems to be a deep longing for something and I don't know what it is. Since most of my writings have been about singleness I could tend to blame it on that. I don't think that is what it is though. I think that could be a fruit longing that makes me aware that there is a deeper root longing. David Wilcox has a song entitled "That's what the Lonely is for" There is a line that says "when I get lonely now that's only a sign, some room is empty that room is there by design if I feel hollow that's just my proof there's more for me to follow that's what the lonely is for" My soul feels hollow. I have tried to fill the hollow of my heart with friends, doing well at my job, feeling loved and admired by others, but I have not really held on to the one who made the lonely and longing. If I am honest, I have ran from the lonely I have buried myself in cable tv and movies. Is this what giving up looks like? Is that what the loss of hope looks like? Nothing so obvious but ever so subtle a loss of hope and belief of my father longing to give me good gifts.
