I'm going crazy - it's now eminating itself physically (don't say it) as well as mentally. *insert appropriate joke here*

 I'm kinda itchy all over, ......my head, back, arms, legs, stomach, and I just dont know why!!?? 

It's been coming on for over a week now, and I can't think what it is?? 

There's nothing at work (nothing living anyway)?  We've had a few nice country walks?  The people that rented the shoebox before us had a dog, no matter how much I vacuum there always seems to be the odd little white hair stuck to dark clothing??  I'm sure nits don't effect your body do they?  Fleas?? Cooties???  (But no-one else seem's to be itchy)??  I can't think that we've changed washing powder or anything??  Am I infested??  *eeek*

Mmmmm??? Is it.....er....no, that can't be it.....*scratch*.........how about...nope...don't think so......*sigh*

Errrr..........maybe it's psycho-sim .........physcho-san.........phsychosym............all in my head?? (Or should I say on my head, and various other bit's)!
