Mel - you listed several reasons why you couldn't do anything for yourself, I get the business, I get the lack of sleep, and the million things you have on your plate right now.
But those are actually reasons why you MUST do something for yourself. Simply to recharge. Even if it's painting your toenails or -gawd, I dunno- as long as it's something purely for you. So even if you don't feel worthy, treat yourself as if you ARE.....or I'll enlist all your friends to harrass you.
