Hey Amanda, welcome to the board. You'll find great support around here and lots of good information.
It sounds like you're having a really rough time of things emotionally which can cause alot of extra stress on your body. Your reactions don't sound so unusual to me as it's obvious your folks mean a great deal to you.
I get the feeling from your post that you may not have an MS diagnosis yet or that you haven't yet been to a neurologist? Have you been to your regular doctor? Usually that's where you start. Your PCP will start with the full physical, run all your labs to determine if anything is out of kilter and its even wise to see your gyn and get that physical order too. A neurologist is highly specialized and I know for me, he was the very last doctor and only after definitive symptoms occured that would warrant his services. They're fairly expensive too.
So I would say start at square one and go thru the process... let it unfold so you get the right answerss the right way. MS is tough diagnosis, it usually takes a long time and lot of patience to get to the conclusion. I actually hope you find out it's not this. Believe me you'll be so much better for it.
