Today I came home from school feeling sick. I had and still do have a stomach ache that it hurts to take a deep breath. My dad also said I looked pale, and I felt like throwing up. I'm planning to stay home from school tomorrow because I still have the same stomach ache. The problem is I always feel terribly guilty when I stay home. I'd be able to catch up in my classes easily and make up the things that I've missed. But, this also means that I cannot go to work. When I called into work today saying I'm sick, my boss hung up on me, and usually she's much friendlier than that. Any advice?
