I have taught several lefties to knit. Since all the patterns and instructions are for knitting 'rightie' then it's best to learn that way.
You might want to try knitting Continental style since your left hand holds the yarn.
Hang in there! It will feel awkward at first, but the more you knit, the more you'll adapt to make it easiest for you.
