Try not to get discouraged- you are correct that there is often more than one way of crocheting. I am an experienced crocheter so I have not visited the crochet sites that offer instruction.
But I am a new knitter & I was confused by the many different ways of knitting. I found the style that worked best for me (continental) & then just practiced alot & made alot of mistakes at first. So then I googled again & learned what I had done wrong & corrected myself. FYI- I was doing yarnovers wrong- it seemed like such a simple thing to do, but there is more to it than I thought.
I personally do not like single crochet (SC), as I can't seem to get a natural rhythm going. My favorite is half double crochet (HDC) because I like the pattern the stitch makes when you only use HDC to make a scarf, hat or purse.
I also find having a picture of the method near me while I am knitting helps me until its sunk in to my memory. Your local library might have a book that you would find useful.
If I could teach myself to knit- you can teach yourself to crochet. We're here to help.
