caregiving and having a life

What I find hard is becoming a little clearer to me as I recover from the stress of Friday's trip to the emergency room.  I don't have the energy or attention to do much this weekend and I feel low.  Part of it is that I'm now worried about my plans to go to a professional conference next weekend.  But looking at my feelings more closely, I realize that nothing seems important to me.  And yet this isn't a short-term emergency where I can put other things aside, this may be the next 10 years of my life.
