Hi Biogirl7 and welcome to NeuroTalk!! Don't worry......the atmosphere here is v-e-r-y laid back. Just visit The Stumble Inn (where us MSer's go to play) and we'll prove it to ya!
Really though, I'm sorry about the dx - you're so young! There's alot of really wonderful people here on this board and I think you'll find it very much to your liking.
