By what you're saying, I would gague your stress at high right now. Sudden tears over small things are a big sign to me that I'm not doing well. With being sick so much, I think that might be a big trigger right now. Plus finding out about your job. You've got a lot going on that will kick stress into high gear.
Time to take some Lia time and pull back a bit. Drop any unnecessary tasks in the "later" bucket, and just take some time to do things that relax you as much as possible. Maybe put your support people on alert, too, just in case. Once you get that infection removed, you'll feel better, I just know it.
Give your soul some rest time, sis. Everything is going to work out.
