You're a frosh in college means that you will have a lot of time to figure out what you want to do. Yes, you may have started to develop a dislike for science, however, and I'm assuming here, that's only because you don't have the broad based knowledge of having taken other courses science, humanities, math, etc.
I used to tell people I disliked cell and molecular Biology, (I'm ok with ecology and evolution b/c of the game theory concepts) that was me like 3 months ago. Even though, 6 months ago I decided to change my whole career goal from finance to health care (long story...). Yet the past 6 months I have completed Gen chem and O-chem, which I enjoyed and loved!!!, I come back to reading the cell and molecular bio in the intro bio books and found out how much more sense they made; all those nitbits in about proteins, carbs, and lipids just became much more fascinating. That's not unique to only chem and bio, e.g. some people who got a taste of the history of science also felt a better appreciation for science because of the long and arduous road it took to make those discoveries, albeit how simple it may seem.
Hard as it may sounds health or even any science career may not be for you, or most people in those major. While I agree with the prior poster in saying you should re-evaluate your career, but you still have time to wander around. So maybe one day you'll take a subject that leads you to a better appreciation of it, or maybe not. I know a lot of people majoring in biology who just wasted 4 years of college, some with great grades, some just barely passing, looking back and saying "wtf I did with my time." If after some time of taking these subjects you realize you just really want to disown your major, then don't force yourself to do something you don't like...there's no point in it.
