I know how you feel, Wii! I get so tired when on the chemo, and yet have to find a way to keep busy enough not to obsess. Different scenario, but I just want to empathize with you regarding one's health vs emotions. Going back to uni has helped a lot, as I bet being back as work has been. Something else to focus on.
Take care.
