My life has been somewhat where you are, as well. When you are used to constant "doing", either in crisis or tragedy, once things calm down, it is hard.
When I found myself kind of lost earlier this year with no outside schedule imposed on me, I made a different kind of routine for myself. I walk on the nature trail for a period of time in the mid morning, then read the paper, work on my quilting projects, do my errands to the store or library, spend more time outdoors in the afternoon, work on my quilting again or bake and soon it is dinner time.
You have been through an enormous amount of change recently, plus the many years of parenting your children with their special needs. It will take you time to "find yourself" again. But, it does happen. And, having a guardian angel watching over you is a wonderful thing, indeed.
Take good care.
