Today I have gone from:
waking up all lusty and then having to wake up DH first thing with my desperate horny pawing 
, to:
feeling like the happiest woman in the world all snuggled up to DH, and then about half an hour after that 
, to:
wanting to stab everyone at the council for not delivering my new recycling bin (all the neighbours got theirs, it's not fair, WAH 
), to then:
crying because my shoes annoyed me 
, and then:
crying again because a nice colleague brought me a bit of shortbread because he felt sorry for me crying at my shoes , to:
wanting to chew my own arm off and beat a different colleague with the wet end for not being able to grasp a simple concept (I know, I'm horrible, I should be more patient), to just now:
despairing of ever being a nice person again 
I am 17 weeks. It's not just me is it? Please tell me it isn't.
