Take a deep breath, you're not alone! I found patho to be one of the more difficult courses I've taken so far in nursing school. It requires that you tell a story and if you forget one tiny part of the story it can make it really hard to figure the rest out. Can you talk with your professor to see if s/he has any suggestions? Do you have access to a tutor through the school or separately? Do you have a study group you can work with? You can do this, you may just have to shake/change things up for this class. Go get 'em!
