3 sciences A lvls +maths

How hard it is to do biology, chemistry and physics at A level is the work load too much or manageable?
I want to go into medicine but i have to pick chemistry. Im really bummed out as I hate it so that means I have to drop physics or maths. I really like year 13 physics topics so im wondering if the work load for the 3 sciences is managable.

In which case, are you sure medicine is for you? Medicine involves significantly more chemistry than biology.
If you already hate chemistry, you will have a hard time getting through a degree in medicine.

Thing is, im not too sure now. I only say I hate chemistry as I feel that if I do Bio and Physics with Chemistry, it would be too much. And since I like Bio and Physics a lot more, I tend to say I don't like Chemistry. I also felt like I never fully grasped Chemistry even though I got a 7. Im just scared that I won't be able to do well in chemistry a lvl
I may have to think of other routes but all my life I've been thinking of doing medicine so Im really not too sure on where to go at this point
Thank you for your response!
