another wave of panic

I am so sleepy. I need to work on the revisions of my powerpoint. It is 60 pages now and it took me ~3 hours to talk about 51 pages. I need practice at least two more times, but I have so many things to do before I can get down to that.

Today one of my committee members successfully made me feel bad about my work. I know it will be ok eventually, but I hate how it feels now.
