Organic chemistry is just about the hardest class you'll take as an undergraduate student. If you don't get an A in this class, medical schools will see it as a sign of weakness and will immediately throw your application away. It's a hard truth, but really, who wants to be treated by an imperfect doctor? Or even more, who wants to train an imperfect person? Answer: Nobody.
RIP OP... med school dreams out the window. Time to quit while you're ahead and start paying off the student debt you accumulated pursuing this neurotic fantasy...
