Is anybody out there Happy ??

What does it mean to be happy ?? I have lived long enough and hard enough to know that happiness is made and not FOUND. BUT right now it seems completely out of my reach. TOO many bills, too many health problems, too many responsibilities. I hate what I'm doing for a living! I feel so terribly isolated and alone. My children are growing up and leaving home and that makes me sad. There are things I would like to do for fun but there's no money! For the first time in a long time I have real physical needs that I don't know how to meet like paying the bills and I really need a car! I have always been independent and not having a car really really stinks! Where I live there are no buses, trains or taxi cabs. You don't have a car... you don't go and everything is too far to walk! I feel like I've really screwed up and wasted my life. I can't seem to find any direction that feels right. I just don't know what else to do.
