I'm a serious case of OCD myself, I've learned to deal with it though - no
thanks to CBT which is a load of utter codswappol.
But it's clinical sterility that bothers me, not tidiness.
Tidy stuff is still dirty.
Something sitting on its own for 30 minutes gathers enough dirt for it to need cleaned before it can be eaten from or used for food preparation.
I'm so tightly controlled and focussed on every tiny detail myself, that I love the expression of freedom of the abstract and wild - I just can't do it, and I'm so jealous of those who can express it.
