Sixth form advice

Ever since I was a kid my dream has been to become a doctor. I've chosen biology and chemistry for a levels but have also been told to put down physics, and I'm just really stressing out because literally EVERYONE on here hates those subjects! To make matters worse, I'll have to do physics at an all boys grammar school which makes me really nervous and anxious, because they're like Einsteins over there.
I did my GCSE mocks, got a B in Chemistry and an A* in both biology and physics, and I'm just waiting for the actual results....can anybody give me some more insight on the subjects? Would a tutor be useful? What's the workload like? And how much maths is involved/to what extent? I'm TERRIBLE at maths - did early GCSE in year 8 and got a C, just about scrape a B now.

PS. my school have decided to make us only do 3 A2 subjects and nothing at AS because of the new system. That should lighten the workload, right?

Much appreciated! Thank you.
