No one (especially not me) bombarded you. I simply gave you the facts (with citations!!! And original sources in case you want to read the information first hand instead of taking my word for it) that you need to move forward with your planning.
Stop being so defensive–we’re trying to help you. We’re especially trying to help to avoid expensive mistakes–like paying for useless coursework.
FYI, You're not the only student to have a tough schedule in college. Most pre-meds will have several semester/quarters of science-heavy workloads. In fact, med schools want to see applicants who have had tough schedules because the workload in med school is brutal & unrelenting. Med school admissions intentionally selects for students who have demonstrated they can succeed under heavy academic pressure.
That sort of schedule you mentioned having is just small taste for what you'll get hit with in med school where you'll be taking the equivalent of 24-40 credits of nothing but upper level sciences every trimester/semester.
