Being a medical student while depressed sucks. You have to endure the everyday rigors of med school and life at the same time. Some will see you as a happy person, but deep inside you are broken.
Some will see you as an apathetic student, but little do they know how you are struggling to pull yourself together. Once you're already convinced yourself that you are somewhat healed, you regret all the lost time you spent worrying and breaking down.
