Hi. I was diagnosed in January 2006 and by March of that year I was medically retired by my employer, fortunately with good salary insurance.
It took me about 18 months, with counselling at my local MS Society, to adjust to the fact that I had MS and that it was incurable. People used to say 'go and enjoy life you have the money'. I wasn't ready to stop work 20 years earlier than I expected! Once I got over 'the shock' I have maintained a positive attitude. I have continued to play guitar and keyboards (I initially told myself I couldn't do this anymore) with adjustments to my technique for the loss of some dexterity and strength in my hands. I am trying to compose an album of my own compositions; I bought software fro my computer that lets me record my music. I also did a lot of reading in the early years.
I kept an online journal (this site can perform the same function), which provided an avenue for me to express my feelings and anger while I came to grips with the MS diagnosis.
There is a purpose still to our lives. Don't let the illness define your life. While my health remains pretty good I have been travelling which gives me positive things to look forward to. Try not to get down, I know depression can be a symptom of MS, and it is a hard place to come back from. Try and remove all negativity from your life, like negative friends and family; my marriage broke down and getting divorced removed significant stress from my life.
I hope there is something useful in this post for you...

One of the great things about being in a service organization (like Rotary or Kiwanis or Lions) is that you have the opportunity to be around great people who are doing good things in the world. I'm a Rotarian and that definitely gives me joy. Certainly much more joy than anything I could buy. Find a group that works on something your passionate about. Even if you only get involved a few hours a week, that will do a lot for your spirits. :-)

Yes, i ask myself the same thing. You are far from alone. I feel like i am even with a family. Not that they arent there for me, but my head still tells me i am alone.

I'm still working currently but I am so afraid of the day I have to stop because I know I wont know who I am. That's sad I think that I've let my profession define my identity but I have. This is my greatest fear in all honesty.

I think this is a very difficult one. I am a Nurse Specialist and have been in nursing for 30 years. There are times when i wonder how much longer i can keep doing the job especially with the hours I put in (8.15 - 7.15 today). However after 30 years i'm not sure what else I could do. Being a nurse is so much a part of who I am. As a nurse specialist in a long term condition (not MS) i do know how patients can really struggle when first diagnosed. Perhaps setting up a support group is something to focus on. Sometimes all patients want is to talk to somebody who is going through something similar.
