Thank you so much for your replies!

Sparky, my avatar is the Scottish wild cat -- they're quite rare and timid animals so it's not often you'd see them. I'm so relieved to hear that the crying is a symptom with these kind of things -- I thought I might actually just be losing my mind completely!!!

I am based in the UK so I'm not sure whether there would be any equivalent financial support for another MRI. My GP won't re-refer me for anything now. They said they will not do any further tests.

I have another question though: Do symptoms fluctuate with MS? My speech can be different from one minute to the next. It's worst when I'm standing up, moving about or doing anything physical and generally returns to normal after a sitting a while with my feet raised. Does that sound at all familiar or not?
