Is football not for me?

I'm in love with music, its my passion. So I did band, but was recently screwed over by my band director so I went back to sports. This is my junior year and I'm tying out for varsity as a free safety. But football isn't as fun as I thought itd be. Its making me realize how weak I am compared to other dudes my age, and I'm not as good as I thought. Pretty much its not fun, I'm more of an artsy person. I really just wanted to hit to let out some anger. Any tips? I'm considering quitting.
