MS and SSD

If you're not able to work at the same capacity that you once did, you are eligible for Social Security Disability benefits.

SSD is different for each of us, and is not determined by if we are in a wheelchair or not.  It comes down to if you can or can't work.  I too suffer from fatigue, it's a hard one because you can't see it, and it's hard to explain to someone.  If you think it's time for it, it probably is.

Personally, I'd keep working as is until you really can't.  I've had MS since January and I've seen my work ability change but not to the point where I can't do it anymore.  I'm a firm believer in a full day's work and until I can't completely do that any longer, I'm not going to give into this disease.  That being said, everyone is different and if you feel you can't go on anymore, by all means take advantage of our government's help.
