Well shirly if I tell you, you will deffo write me off as a loon.
So anyway.
When I clean I get an andrenaline rush. I get that whole endorphine thingy going on. I also feel a bit teary and stuff.
Hang on there is more....
I didnt used to be like this. I was a total slattern who wondered where all the dirty washing was coming from and what that brown stuff on the floor was...
But then a couple of things happened. DS2 arrived aged 8 weeks old and with him a mob of social workers, physios, contact workers, OTs blah blah blah in my house most days. The long buried working class chip emerged and I 'wasnt going to have any of that lot judging my house keepin'
Then my DD got sick and her immune system fucked off. Even though she was more at risk from internal infections than external, i got it into my fevered brain that if I cleaned the house all the time I might just keep her alive. Her illness also bought its own quota of nurses, physion, Ots etc blah blah.
So I cleaned everyday, top to bottom before 8am everyday. Apart from when we were in hospital and then I cleaned the ward 
So 5 years after losing my lovely girly girl I am still at it. I am not as menkle but I think my brain just triggers something weird when I start cleaning. Its like having a glass of wine and makes me feel all sort of wooooooo for a bit.
Bet you wished you never bloody asked now dont you!
