Sick with worry

Insomnia.
Anxiety.
Nausea.
Headaches.
Chronic, dull low back pain.
Lack of focus.

I really need to get my mind off my situation, but I feel that if I don't work tirelessly to solve it, I will have failed myself and my daughter.

I know there comes a point where you can't do anymore than what's already been done, but I'm not sure if I've reached that point. I have this nagging feeling that I missed something, overlooked something, didn't do something right. It's extremely stressful. And distracting. And emotionally draining.

Or maybe I feel like crap because I'm coming down with something. Time for some tea.
