Kelly, relax! I know easy to say but this is so in your heart and you want to do it, that's what makes it special. Those kids are not stupid and neither are the "judges"....they will see your spirit shinning through. If this is something you still want with all your heart they will feel that and sense it too. I think that would make a perfect teacher. The one who really cares and gives it her or his all.....as a parent I just knew and so did my kids. You'll be just fine and you are one of those special ones that will make a difference.
