schedule, what?

I am having a real problem putting myself on a schedule. I am running around in circles and quite frankly feel like a dog chasing its tail. Nice visual, huh?

Here's what must get done every day:

• Feed and bathe my children.
• Pick up and drop off my oldest at school.
• Take a shower. (Although this has been optional lately.)
• Dinner. (Ugh. Why is this so hard?)
• Exercise. Not only for my physical and mental health but for my 1/2 marathon in June.
• Work. I work for 2 AVON District Managers from home and have stuff I must get done for them on a daily basis.

Stuff that is only getting done when it absolutely must:

• Laundry.
• Picking up around the house. Don't even get me started on actually cleaning.
• Me eating breakfast. I know.
• Couple time with my husband. It's been practically non-existent. Not good.

So what do I do? The stuff that must get done isn't always getting done (although no worries my children ARE being taken care of) and it's stressing me out. I've had a migraine almost every day for the last week and a half. It starts as a tension headache and spreads from there. I've seen my chiropractor who has confirmed what's going on but I don't know how to fix it. When I get a migraine I cannot function. At all. This puts me even further behind and makes me stress out even more. See the cycle? I need to put myself on a schedule and stick to it before I lose my mind. Any suggestions on how to start would be greatly appreciated. Because at this point I'm so totally overwhelmed that the only thing I find myself doing is staring at my crazy long to-do list and, well, doing nothing.
