Similar thing is going on with me right now, since I burdened myself with electing myself to care for her.
The draining effect has robbed me of motivation, I must of caught it from her, all she does is eat and then sleep, not even washes herself for days.

What gets me frazzled with my lack of motivation, is I had started with so many plans to do things in my house,yard and even community, but now I barely have anymore oomph!
My pdoc attributes the emotional stress to be the draining force of any motivation I had.
Whatever, I went through this a few years ago, way before I brought my mom up from FL after dad passed away, so I couldn't tag this on her. It just really sucks when motivation get sucks from us.
I hope you get some little spark of motivation, I have found it can jumpstart things, not always but whatever we can gain from a little spark is better than nothing I guess, eh?
Lots of luck with this. Anyone else have any ideas or suggestions towards gaining motivation? Please add to this thread.
