Am I wrong for thinking this?

Last night I got really badly injured- and I can't dance for a while which made me really depressed. My best friend (we'll call her Emma) is always there for me when I'm feeling down. I spent the whole day at home maneuvering around on crutches and in horrible pain and boredom - I found out she had spent the day at the girl who no one likes in our group (We'll call her Hannah)'s house. Hannah knows no one likes her and Emma complains about her all the time. Am I wrong to be pissed off that she didn't even bother to call me and ask how I was doing, much less show up to make me feel better?
