Advice on becoming a CNA?

I’m considering dropping out of college. I keep failing Anatomy and obviously I can’t get accepted into the nursing program without it. However, I feel if I can’t even do basic Anatomy I sure can’t do a thing the nursing program would require. I have my CNA and I’m wondering what life would be like if I just made a career of that. Is it really as bad as people say it is? Is the money worth all the butt wiping?
