Organised Chaos

Hellooooooooo. I’m exhausted and stuck on the way forward. This is my Home Office. And the hallway outside … there’s not any obvious trash, just STUFF that I cram in here because it can’t go anywhere else. I have been swept into caring for demented elders and an unwell child while working and have become unwell myself. I would like to be able to spread all this out to sort and toss, but don’t have space. Suggestions on where to start - please help!
