I, too, am a lefty and I honestly have no idea how I could learn to left hand knit. I do some things very different than I should, I guess. I definitely don't do english method, but my continental is kind of...interesting. I never, ever got the trick of holding the yarn wrapped around my finger, so I lift the yarn every time. I'm a hopeless case. I'm knitting an afghan right now and having to lift it every time for 200+ stitches a row is tiring.
Don't feel bad it took me about 8 years to get how to the hold the yarn and then about 9 years to learn purl lol. There's always hope, I'm sure you'll find a way that suits you eventually.
