First, make sure you follow Sebas' link for a great place to start learning Unity, however I'm adding this answer because your question seems to particularly focus on asking for advice based on learning programming at a young age.
I'd suggest that learning programming at a young age is probably a great time to learn, and in fact rather than it being a hinderance it is probably an advantage, since you have masses of free time and a brain which is perhaps eager to soak up information much more rapidly than some of the, *ahem*, slightly more fossilized community members here! (I started learning at the age of five, when my Grandad got a ZX81, and we'd copy listings out of magazines together.)
Just make sure you balance it out with a healthy amount of time away from the screen - you're only young once!
I have posted a collection of learning resources and tutorials here. Some of them are text-based tutorials so you won't have problems with understanding somebody's voice. The resources listed there should cover everything from absolute beginner to advanced user, no matter what your age is.
