I think I subconsciously love negative attention

Case in point- A child is being transferred out of my class tomorrow. This child (and parents) have already caused me much agony and stress... and it's only day 5 of school. I even have said " @ this point I don't even care if they transfer her b/c she is causing me so much stress". Yet when I find out she is leaving, I get this twinge of sadness/guilt. I feel like I didn't do enough, didn't succeed as a teacher. See ? I love negative attention...
