Singing Low and High Notes

I like to sing. Simple as that. Yet, I kinda suck at singing really high notes and low notes. It's understandable; I am a soprano. But I like singing low. I like to be an alto instead of a soprano. Yes, singing high notes are fun, but with a alto voice, it's fun. Maybe if I practiced more, I could reach both notes? Like how counter sopranos reach super high notes, and altos reaching low notes. It hurts to sing low, but someone once told me that I'm going to need air to breathe to bring the sound out. That's what I'm gonna practice. Breathing exercises!! >O< I hope I can reach the low notes soon! It's fun singing those(along with high notes)! Wish me good luck! :3
