If I were back in gradeschool I would have taken advantage of something like this, but if I were you OP, I'd advise against it. Because all you're doing is pushing that fear down the road. You are going to have to speak in front of groups and give presentations and all the rest of it eventually, so you may as well learn now. Is it scary and stressful? Hell yeah. But it's also the burden you have to bear, and if you learn now, future you will be all that much better off for it.
