Lonely People lyrics

I just don't seem to be able to figure it out, what the heck is the "silver cup" and where can I find it? I couldn't imagine any other song other than LONELY PEOPLE that describes my life clearly. Even though I've had great jobs, money, cars I also had a drug history that I allowed to rob me of my 20's and 30's. I still find myself more alone than ever. I've been blessed with a great job that I contracted for in the current recession, but I am the visible man. I smile often trying to find peace, I truly love working with and assisting those less fortunate than me which is my vocaiton, I get to work early and leave late of my own choosing, I extend respect to others as I would wish to be respected, and I'm still the guy who doesn't get invited to happy hour on pay day. What is it that I've done wrong? I try and try and God seems to roll me in the punishment phase continuously; it seems like pay back in the theme and I'm separated from any group despite my best efforts to fit. I often think of the things I have done and failed to do, and at 44, I'm the guy who has never been asked to dance or picked up in a bar, ever. I feel like a rock in a desert on a barren planet. I have none to go home to except my cat and no one calls. My days begin and end in isolation despite my efforts to not only be true to myself, help others and do the right thing; I'm the odd man out and I hate it. Every breath is a gift, but is underscored by a staggering amount of personal pain and God still sees me fit to dwell in unending desolation. I want to have friends, but no matter how hard I seek happiness I end up short and I've run out of words to say except for this, I wish the best to all the lonely people and God bless.
