So Sorry for your Loss..
I totally understand.
When my Mom passed away, it took me a while to want to do much of anything. My sister found me sitting on my lawn mower one day beside the house. I set out to mow the yard, but just had no energy to do so. All I could do was to reflect on her. Work kept me busy, as I was just working in a fog, day by day.
When I found medium, and this great community, that was one of the best thing for me. Well that and my prayers.
I still miss her, but I can feel a cool breeze at times, as if she is telling me, it is ok, to move on.
I hope any of that helps. The main thing is, to keep praying, at lest it was for me.
AL.
