Is It All Worth IT!?

Here I come again at the point of thinking things over if it is all worth it. Is it all worth the pain? emotionally, physically, mentally? is it? They ask too much from me things that more than one person should be responsible... things that a higher person should be responsible. At this time I can only think of one thing..... to break off..... I feel that I am chained, like a slave, I havent felt rewarded for a long time now and yet I have not complained to them, not a single word but only to my self.
