So I've been on here for a few months now, but have felt a bit nervous about posting... here goes nothing.

I've been an emet for just over a year now, and it's acting up right now like crazy. There's a really bad stomach virus going around at my school that attacked everyone (mostly boarders) this weekend, and I didn't know about it until I got to school today and noticed about 30 out of a total 240 students out with it (it's a v one, and it's REAL bad). What can I do to keep myself from getting it? I haven't eaten at all today because I've been so terrified, but I know that's not good and that could make me feel worse. Is the stomach flu an airborne virus, or do I have to ingest it? Should I just not go to school tomorrow? I'm so scared of getting it
