Well, as many have said before me, ‘congratulations and commiserations, welcome to the club that no-one wants to be in’!
The wheels of neurology can turn very slowly, so I would suggest that you call your local hospital and ask to speak to an MS nurse. I know that in my area we can self-refer and all they have to do is check that you’ve been diagnosed. They also work closely with the neuros and the ones I’ve met so far have been lovely.
As for benefits, it very much depends on how your MS affects you and your ability to work. You’re welcome to PM me if you have any specific questions.
There are a lot of misconceptions about MS, so just try to bare in mind what you would say to someone in your position, not knowing what you do. I’ve had people send me links to articles where someone cured their MS with diet/exercise/Lightning Process etc. and people dissolving into tears thinking I was going to die. The thing is that your MS is specific to you and no one else.
Also, be kind to yourself. Whether it was unexpected, or even a relief to be diagnosed, our brains are unique and deal with things in their own way, so don’t be surprised if your reaction to your diagnosis changes down the line and accept that you may need help to deal with it.
