I don't feel I can add any direct information or advice to the other times you've posted this question in the past couple of days. JJ and Lulu both offered good advice.
Have you received your appointment yet? You mentioned you might find out about that on Thursday. I would shift focus to putting together a symptom list and timeline (information and tips are in our Health Pages
http://www.medhelp.org/health_pages/Multiple-Sclerosis/The-Importance-of-the-Timeline/show/765?cid=36).
I'd also recommend pursuing ways of mitigating the enormous stress you might understandably be under. Thoughts of MS and definitely ALS are putting the cart before the horse at this point. Easier said than done, but do try to find ways to get out of the 'what do I have?' headspace a little bit every day. I know whenever I want to give my brain a rest, I put the laptop away and go outside, read a book, meet-up with a friend, do some mindfulness practice, potter around on the balcony garden, etc. Having a high anxiety level majorly reduces my quality of life, so I throw the kitchen sink at it if it starts to creep up.
