I suck

...at school. What am I even doing in grad school? :( I led a discussion with my group today in one of my classes... the whole time I (sort of) felt like I didn't know what I was talking about... or at least, I felt that way... most people told me I did fine... I don't believe them. All this makes me wanna do is work harder... because I just feel like I'm not doing as well as I can...
