I'm also new to this (diagnosed in april at age 40, started on rebif in may, found this site a week or two ago). I found it was real easy at first to max out on info, but have found these forums to be very useful.
Of course the psych part is the hardest...you're bound to be depressed, scared, bitter, etc. at times. Being diagnosed with MS is a lot to absorb and is a major "life-change." If you think it'll help you, you should ask about antidepressants and/or counseling. The uncertainty of the future is the hardest part of ms for me. I don't know why or how, but I've recently developed a better acceptance of the unpredictability. There's very little in life we have real control over, with or without ms. I think we tend to delude ourselves. MS is my reality check!
Good luck with sorting out the info you need, managing your health, and raising those kids...As a non-parent, it seems like raising kids would be the real challenge!
