Like you I was diagnosed in my 40's at 47 I had pretty much worked it out for myself by the time i saw my neuro but it still was a huge smack in the mouth. I have since then June 2013 been in study mode learning as much as i can cope with to me knowledge is power it enables me to help me as well as anyone else whom may be struggling.
I within a few months joined my local support group branch in Lincoln and can honestly say i would have cracked under the strain of it all.
i am now on the committee and also run with another member our local working age group and I am the youngest member of the branch at 50.
Having someone to talk to whom is going through the same sort of thing as you has really made a big difference to me, I wholeheartedly recommend joining your local branch if the members are anything like ours in Lincoln you will not go wrong.
If you need to talk feel free to private message me and I will be only to happy to help in anyway I can.
