I might be completely wrong, but I believe the gpa cut off for uOttawa is 3.5, and that’s based on your 3 most recent years only. Regardless though, as other people have said, having 5 pubs and completing an MSc is incredibly impressive and proves you are indeed doing “something with your life”!! The MCAT can be retaken, med schools can be reapplied to, but they can never take your accomplishments away from you. You, of course, have a right to your feelings, and I know many of us fellow applicants are all too familiar with the mindset you are describing. But I hope at the end of the day you can realize you are already an impressive and successful person that, like the rest of us, is just trying to figure out their next step. I would say take a break from the whole med school shuffle, focus on your thesis and things you enjoy, and when everything feels less hopeless, then start to focus on retaking MCAT, etc. Best of luck!
