Good morning and good for you!
Taking medication like Xanax can be a pretty slippery slope. And trust me, you do not need to be comparing your usage to others. I've heard horror stories of heroin and crack abuse in N/A meetings - that didn't mean my own alcoholism wasn't a problem. You seem to know that you're not using your meds as prescribed, and you're worried enough to be here...that should be enough for you to start working on getting well. Let us know how it's going.
