MissHairspray, I was the same, the day I got the BFP's I was walking on air, then it all kind of slipped away to nothing, and left me feeling really down in the dumps, which I am not used to, and no good at!
I had a MC in January, and I think that is having a big bearing on it, but even so, I can't seem to even muster a small smile to myself.
I am not usually so bloody gloomy, it is starting to annoy me now!!
