There are many, many ways to find a passion (and a career path). I was failing badly at Physics, and stumbled, almost accidentally, into programming. I found it easy! And I had a great career as a programmer, doing things that came naturally to me.
So here is one problem you do need to solve: find something that you do know how to do and put your energy and passion into that. (By the way, I cannot play a musical instrument either - and I have tried over and over again. Love listening to music, just cannot learn to play it).
