Appendectomy - out for 2 weeks

This sucks. I was running last Tuesday and felt a little cramp on my right side. Then I woke up Wednesday with the worst stomach ache. By Friday I found out that I had appendicitis. I had emergency surgery Friday night and now I can't run for two weeks. Also, I can't seem to get enough calories either. 1200 at most, the last 4 days. only 1000 today so far. I need at least 1600. This sucks
