Wow, you've been under a lot of stress. You only stayed home 3 days?
I had been laid off from my job, (unexpected and unwllingly), my cat had decided to become anorexic, and as I fretted over how to keep her alive, DH said, "You're going to make yourself sick." As soon as she started to eat again, I became nauseous, chills, fever, funny little rash on my back. The Dr. was rubbing her hands together, saying, "Classic, the symptoms are classic." I felt like death warmed over for five weeks. If I got up at six am, I needed a nap four hours later.
Here is what helped me feel better: Make sure you have good food for your body to repair itself. I don't know what you do, but try to eat something every four hours. You don't need to eat more, just divide up your meals so you're never running on empty.
Oddly, the five weeks I ate every time I felt ambitious enough to walk to the kitchen, I lost five pounds.
