One problem I have with my son and decluttering is that he gets extremely anxious about the idea of throwing ANYTHING away. Even, say, the wrappers and cardboard box that his Pokemon cards came in. And he kind of panics if I tell him I am going to clean his room without him present. But if he is present, I'll pick up things and ask if we can throw it out, and 99% of the time, he says "no" and takes it and shoves it in a drawer. Old rubber bands, scraps of paper, whatever. I do wonder if he has some sort of hoarding disorder.

I'm not tidy, but I don't have any problem parting with objects.
