Put it in a Box

Why do I feel the need to organize every little thing and contain it away in a container of some sort?  Please explain it to my husband.  His name is Joel.  He doesn't "get it".

I don't know where this obsession comes from.  My mother was a neat-freak and my dad came from a long line of disorganization and semi-hoarders.  I always felt more comfortable with Dad's family, even though disorder causes my brain to feel overloaded and messy.  This only happens when it's my own; other people can live how they want to and I don't even see the little (or big) messes that occupy their homes.

How can I explain this to Joel when I can't figure it out myself?  It's not even that I'm that organized.  I just figure if it's in a container, it's 'contained' and not spilling out everywhere.  Problem is, now I have all these containers with unorganized "stuff" in them. 

I'm hopeless.
