Hello Clem :)
Very sorry to hear of your diagnosis - it's a lot to take in. I was dx with RRMS in 2006 after a similar diagnostic route - MRI of brain and spine showing 2 periventricular lesions and 3 cervical spine, LP positive for oligoclonal bands. I presented with dizziness, MS 'hug', sensory symptoms, neuropathic pain, bladder issues, tremor, some niggling eye pain/flickering, blah blah blah - timeline from first Neuro consultation to diagnosis, following Macdonald criteria, was around 18 months.
If you're in the RR camp (which it sounds like you are), next step could be to think about disease modifying drugs. I've been on Rebif (injecting 3 times a week) from point of dx until recently - have come off because we're thinking of having another baby. With DMDs, if you're comfortable with tackling it with drug therapy, the sooner the better is the advice I've always been given. There is not one symptom on my list which hasn't been considerably alleviated by low dosage medication - and advances in treatment options are coming on in leaps and bounds for the future. IV steroids (methylprednisolone) for 3-5 days for relapses, as quickly as possible, make you feel like you been run over by a juggernaut short term, but do see the relapses off in good time.
The MS Society website has a wealth of info and a great community board - I spent a lot of time there chatting things through with folk in the same boat. Everyone is different, of course, but a maintaining a positive attitude has really helped me stay on top of my dx. A wise soul described it to me as not a dead end, just a series of road humps :)
Like posters below have said, please feel free to stay in touch on this thread or via PM. The dx is a kick in the guts, for sure, but 6 years post-dx I'm still well, coping with the symptoms as they come and go, enjoying my DS, contemplating another, working full time, and formulating plans to change direction and go back to college to study Nursing.
I have my bad days, of course! There will be crap times ahead but support is readily available if you need it. One thing you don't ever have to feel is alone :)
