Suze,
I'm sorry you're experiencing so much stress and consequently, illness. When you're having a nice cup of coffee, think about the things that are the most important to accomplish and put your energy towards those.
Make sure you're doing small acts of self care, eating, a nice hot shower or bath, enjoying a sunrise or sunset and getting plenty of rest.
I hope once settled state side, you can rest and focus on getting better. Hugs.
