I'm so sorry for your loss. November is not that long ago. It's okay that you are still grieving. The emptiness may never totally go away, but will lessen some with time... or maybe you'll just get used to it and learn to cope... hard to say.
So start with little things as you feel up to them. Pamper yourself at home or with a trip to a day spa. Pick one small thing you want to do, then reward yourself for doing it. No pressure or beating yourself up if it doesn't happen over nite.
Gradually start to think about your future. It there something you want to do to continue to honor your mother? What was your life's work before you were caregiving for Mom? Is it something you would want to do again, or is there something else you would rather try?
In the meantime, go ahead and grieve. And please do continue to post. We're here to listen.
Love n hugs,
