Being aware that so many symptoms CAN be MS (or just not in your head) makes you ultra-sensitive. I'm sure most everyone here will completely understand. Your long list can probably be made into a shorter one though -- I'd try to categorize them, ie; "Visual Disturbances" would be one symptom and then under that header, explainations of how it manifests itself (and again, at what times or always, description, etc.) These doctors start from an empirical platform and the way that you convey what you're experiencing will definitely impact their initial impressions and spur questions.
Just suggesting this because at least for me, it seemed to be a better way to talk to doctors and make them understand. Finding it especially true with specialists, who tend to be very busy and often a little less tolerant.

In general, I believe that figuring out HOW to talk to your doctor in a language to which they'll be receptive is a very big first step. Kind of not what you say but how you say it -- and hopefully as succinctly as possible. I know that can be a pretty tall order when you're confused and distraught.
