Yeah its weird. On the one hand I feel like I'm doing great and my PhD apps will be desirable and lead to acceptances. On the other hand I feel like I don't really know how to do anything well and that will be totally obvious or that I'll overlook some important step and screw myself. *sigh*
I experienced the EXACT same feelings...a mixture of confidence and anxiety, sometimes overlapping each other!! So I guess we are just weird exceptions...or it's quite normal feeling this way!
