Im a college sophmore and this past semester ive felt awful emotionally. Ive assigned all my selfworth to my grades and performance in school since i need good grades to get into med school. I constantly doubt what i know and feel like im making up what i do know and the only reason i still have a 4.0 is luck and the professors being nice and lenient in grading. I was full of confidence in my abilities last year, how do i get that back? No matter how good my grades are and how many assignments i turn in i still feel subpar and a poser.
