I only chose that because my counselor told me to so I can get into med school
I don't know if your counselor was right or was trying to weed you out.
You can be any major you want to be. You can be a history, art, basket weaving major so long as you have the pre-med classes.
Several counselors I've seen suggest extremely difficult majors such as biochemistry or the major you have did so only because they wanted to shoot that candidate out of the water. Schools known to have vicious pre-med weed out philosophies such as NYU & Rutgers do that which IMHO is a disservice to the students because counselors are supposed to work on the auspice that they are for the student, not the university. I've also heard horror stories of people in schools such as NYU & Rutgers where the counselor did outlandish things such as put $500 on the table in a condescending manner and say to the student, "I'll bet this much money you don't make it in" even though the person had a decent GPA & MCAT score.
Now to be fair, I don't know what school you went to, and there are advantages to what your counselor mentioned. You might be in a school that does not follow out the weed out philosophy in any way.
While you can be of any major, having taken several of the courses in medschool while in undergraduate (anatomy, physiology, biochemistry, histology, pathology, microbiology etc) are of extreme advantage should you get into medschool because the curriculum is to the point where you get about 1 week's material in undergraduate in about 1 day. To have known this material ahead of time is a definite advantage, though at the same time I've seen several do well who had a non-science major. I remember myself, a history major, and an engineering friend of mine all feel lost during lecture--and we had a bad lecturer. The majority of the class already knew the material. I remember during my Immunology class, several people kept muttering "the only reason why I did well was I had this in undergrad. That lady can't teach for beans." Yeah well for me & my engineering friend never had it before, so we were at a big disadvantage.
A disadvantage to such a major is if you're in a weed-out school, most of the classes in those curriculums are weed out classes which will have a strong impact on your GPA. Getting into medical school is a numbers game. You have to have a strong GPA & MCAT score as if nothing else matters. In most cases, nothing else does matter unless your GPA is above a 3.5, and your MCAT is above a 30. Only then do medical schools seem to care about your personality. I remember people being in courses such a physical chemsitry or Biochemstiry, and the average grade being on the order of a 40%, which by statistical standards wasn't even a fair representation of what they knew, yet the university had no problem failing 1/3 of the class--which in effect would've destroyed their chances of getting into medical school.
Medical school is tough, but its not the point where they're failing out 1/3 of the class.
This is why IMHO its little surprise when I hear of so many medical students that went to small schools for undergraduate not known for academics because such schools usually do not have a weed out philosophy.
There are also advantages of a non-science major, though they will not make your life easier in medical school. There is a room for the humanities in medicine, unlike what several cold left brain doctors sometimes say. I've seen several medical school professors project onto students, and want them to be cold, calculating and schizoid people. I knew of one medical professor who held it against candidates if that person came in with a smile to the interview. Perhaps needless to say, but this was a very unhappy person who I thought would make a terrible physician (he was a pharmacologist).
IMHO primary care & psychiatry should teach more sociology & psychology than it currently does. Certainly someone with a background in these disciplines could contribute to medicine.
Again you can be any major you want to be-I mentioned the pros of having a strong biomedical science background, as well as majoring in another field.
