Chiyo, I am so sorry for your most recent loss(and your other one for that matter). Sleep is good, and busying yourself with something.
I lost my dad last week and do not know what to do. I am just tired and very unmotivated. I do have to do some stuff, since I have a family. The kids need dinner, clothes, etc... but I feel robotic.
But I am going to just try to ride it out. Do walks help you? I find walking very helpful when I am depressed or anxious, but the weather here has not been good for it. Maybe you can get out to walk?
I hope you stay strong.
