Dan,
It is not clear as to why you bought an expensive right handed bow when you do everything else left handed. My first suggestion is to sell the right handed bow and get a left handed bow. That will remove MANY obstacles in your shooting. Take the $$ hit if necessary and count it as a lesson learned. It will allow you to learn easier/better if you get it right NOW.
IF you can't/aren't willing to do that, IF you wear glasses, put a piece of scotch tape over your left lens BUT keep your eye open! If you don't wear glasses get a CHEAP pair of sun glasses, knock the right lens out and shoot with both eyes open.
You will have better luck IF you keep light going to both eyes than trying to shut one or patch it like a pirate.
You say you are one week into this, you will have no accuracy to judge for a while so do not judge yourself on that. Keep both eyes open, work on the shot sequence and obstruct your dominate eye but be sure to still allow light to that eye.
