Great advice already
Couple of practical bits to add: you need to tell the DVLA, and check out your mortgage policy small print or anything else that might have a critical health element to it (MS is a payable illness). Worth getting your vitamin D3 levels tested too - a lot of MSers are deficient, and there is a growing amount of evidence that maintaining a higher than recommended level is good for MSers (not that your GP will probably be aware of this! Check out vitamindcouncil and vitamind3uk.).
Getting your head around the diagnosis is not so straightforward
I saw a counsellor a few times and that helped masses, but the only thing that seems to help consistently is time. Experience of actually living with and dealing with MS, realising that life still goes on and is still good a lot of the time, as well as it becoming more “normal” for everyone, gradually does the trick.
I am a big fan of talking, else everyone bottles everything up. People are usually scared of sharing their thoughts and feelings for fear of scaring and worrying the other person. They aren’t healthy things to bury inside so sharing and allowing your partner/loved ones to share too can be really helpful. A problem shared and all that.
Then you’ve got the whole lack of understanding dimension. Most new MSers and loved ones don’t know much about MS - so they are often imaging all sorts of crazy things. My first thought was of Jacqueline du Pre, the famous cellist who died of MS. “OMG, I’m going to die!” Absolute rubbish of course - I definitely do not have the very rare variant of MS that she had! So getting the crazy ideas out in the open so the person can be reassured can really help too.
Not everyone will be ready to talk though. Denial is a well documented stage of coming to terms with the diagnosis. I guess the only thing to do when the MSer and their loved ones are out of synch is to be patient and wait. You’ll come together at some stage. And if you want to talk and they don’t, you can always come on here!
Somehow or other, most of us get through it to the final stage: acceptance. Then we can move on, and get on with the important things in life!
Oh, nearly forgot… re everyone knowing best. GPs usually know next to nothing about MS, but there are some good ones out there. As Poll says, MS nurses are variable. Same goes for neuros. If you have an MS specialist, then they are the most likely to know best. You’ll get mixed advice on forums. There are some real crackpots about. There are also some very experienced and knowledgeable people too. It can be tricky to tell the difference sometimes though! Anyone who starts a conversation with, “Oh, my mum’s friend’s daughter’s boyfriend has MS and…”? Nod politely and tune out! Anyone who says that X is a cure? Ignore. Same goes for any websites that claim they can cure or massively help MS. If you want to know about MS, stick to the respected sites in the beginning at least: this one, the MS Trust and I would also add the multiple sclerosis research blogspot. If you want to know all the latest news about MS, then I reckon the MSRC RSS news feed is the most comprehensive (I don’t read the rest of the site).
In the short-term: take it one day at a time, like Teresa said. You’ll get there.
