Oh hun...big to you...

I totally feel for you. it sounds like you could really use soemone to talk to. Does your GP / Ob know how things are for you atm? Some counselling might be good for you...just to be able to get it all off your chest.

Pregnancy can be a really emotional time anyway without dealing with what you are atm.. it sounds like you still have some emotional pain from your loss 10 months ago, and relationship trouble on top...no wonder you are feelign a bit strung out!

Trouble with DH & with your job...general stress & unhappiness can result in anxiety too...believe me I know... it really sounds as though it would be good for you to talk to someone now before bub gets here.
I would certainly do the counselling with your DH, but make sure you look after you as well...
