Jeff, don't start thinking of everything that has to be done, it will be overwhelming. If you feel up to it, start with the night stand and then go to the closet. Just clean out the closet for now, you know.
I hope all goes well with your tests. As someone who has suffered with debilitating depression for years (yeah, I am sure you are shocked to hear that since my thread is so upbeat - not!), it could wreak havoc on your body. Fatigue and being a pack rat are sometimes signs of depression. It would certainly be understandable in your situation. Take care of yourself, my friend. Our health is the most important thing.
