It's easy to be good at math. Just stop diving into the higher level shit, and re-learn the basics. Start as far back as you can, just to re-familiarize yourself with it, and then gradually step up until trig and calc aren't wizard scrawlings to you anymore.
That said, "computer graphics" requires a bit of math for some of the more complex stuff, but that's a pretty wide and deep field. Could be anything from 2D UI design, to advertisement banners, to 3D models of proteins.
