It is not you who is needy, but the other folks who are needy for a bit of meaning in there lives by helping others who they perceive to be less fortunate. It is a trait that makes us human. So, Ann, I would say to help these folks feel good about themselves by letting them help you. And then you can feel good about yourself for helping these folks out. Or you could be very demanding and unthankful and people would be reluctant in giving you any help at all. You probably don't want to go that route.
I guess all us Parkies have to adapt. I cannot just pick up a guitar any more and play when the mood hits me. So I cope by creating amateur cartoons.
