Welcome Nancy, nice to meet you.

So sorry about DH's DX. It's hard to be the DW and caregiver and to watch your spouse progress with this dam disease.
Your DH is right though, worrying about the future is not productive and the stress can only make the disease worse. One day at a time. Has he applied for SSDI yet?
Is he on any MS meds? How are they working?
I'm SPMS and on LDN (Low Dose naltrexone). The MS meds don't seem to work for anyone who is not RRMS and don't often work for even them.

I always recommend for all of us to try LDN. It can't hurt, unnless you you're allergic and could help in so many ways.
I'm glad you found us stay with us and best wishes for you both.
