The break is over, even if she isn't home yet

We have a few days left, but already I am preparing for school to start, getting her room cleaned, and having anxiety attacks about how I will schedule my doctors' appointments around her school schedule and the absence of anyone to babysit or get her from school if my appointments run over. I have appointments with specialists, and those can be all day events. I am worrying about how I will keep up with her laundry, because our dryer is irreparably broken and we can't afford a new one (or even a good used one). I worry about how I will take care of her if my family doctor's predictions of my final diagnosis come true. I think I am worrying too far ahead, yet I feel like I have to. They say that God never gives us more than we can handle, but I think that being 50 and taking care of a Downs child, being dirt poor, and having a possible diagnosis of MS (and no health insurance) hanging over my head is a bit much.
