You need someone to throw the ball for you.
Anyway Allie, it takes time to learn the equations that you need for full manual. And practice doing it. Many steps along the way.
So starting by letting the camera figure it out on full auto is fine. Then go semi auto with aperture or shutter priority once you understand what an image needs. I'll generally only go to full manual when I'm after something specific with the light.
