I am sorry your like is a living hell, but repeat after me; "I QUIT". See how easy that is. Now your life is no longer a living hell. I just don't understand why you are blaming McD for your problems. We all know the box is more nutritious than the Big Mac that's in the box. We also know McD hires kids. But you have to have the mental capacity to process the facts in your mind and make decissions.
I still don't know why you contend McD is the bad guy. First of all, not all McDs are the same. Second, they are a business needing to turn a profit. And you have the right to move on. Oh, I forgot, you have no employable skills. Silly me.
