You don't need to be dramatic. All
@Goro is saying is that the downward trend in your GPA is not going to do you any favors. Did you expect your downward grade trend to be a good thing?
The reality is that we are all imperfect human beings, and almost everyones application is going to reflect that in some way. There are few, if any, applicants who apply and say "there is absolutely nothing I would change about my application". We all wish we did slightly better in that one course sophomore year, had a few more hours of shadowing, would have had a better response to that interview question, etc. If you constantly dwell on your imperfections, nothing good will come of it.
Long story short: the B's in upper level science courses senior year are not going to help you (obviously), but they are in no way going to sink you at every MD and DO school you apply to (also a rather obvious point). Apply broadly with a well-rounded list of schools, do the best you can during your interviews, and good things will come your way. There are many MANY other applicants who would die to have a 3.6 GPA and a 518 MCAT score when they apply for medical school.
