I usually have a very good appetite - too good actually as I am overweight. For the last few days I just haven't been hungry and have barely eaten.
I don't know if it's serious, or stress. I've been very stressed out with the weather and being cold all day, and then I found that a good friend has been diagnosed at a young age, with breast cancer and I was very upset for her. But is that enough to cause physical symptoms? I know people on here aren't medics, but some might be.
