Happygirlygirl – Why don’t you start off with reading the “Alcoholic Annonymous” book? (You can download it as an ebook or PDF if you don’t want anyone around you to know what you’re reading, BTDT.) While it is written for those with alcohol addiction, the basic principles are identical across all addictions.
The book will give you the basics and bit more insight about the 12 Steps. And as far as meetings, as kapusta said, see if you can find a group online. Once you see what it’s all about, you can make a better decision about joining a live group.
