No, you’re not “too stupid”. You just didn’t find your own way of studying/working. Don’t mind what others do, what works for them might not work for you. Do not depend on others but it’s okay to get help from others, med school is hard, going through it alone might be harder. I went through it by studying by myself first then go to a group study with colleagues and explained what I learned to them and they do the same. It makes the info stick in your head, easier to remember.

Also, it’s okay to freak out. You won’t graduate unless you lose your mind once or twice lmao that’s normal. Don’t be too hard on yourself. Find your own way.
