Do you simply not like math or is it because you are not good at math? You will need to have an understanding of math -- you might (depending on the science area you pursue) not need to be an expert in math.
Like noted here -- the more advanced math will be actually calculated via a computer. You will need to understand the results though.
I, for example, majored in economics. It too is heavily involved in math and stats. The advanced math I was required to take in graduate school was very difficult for me. And I loved math. But once we started getting involved in the very advanced math, I just managed to squeeze through and pass. I was able though in the advanced economics course to use computer programs for various stats, etc. and interpret the results. So the overall understanding is important but perhaps not actually calculating out these huge complex equations.
