depression while pregnant

Gayle
I have a history of depression and my drs are aware and are going to keep an close eye during my pregnancy.
Im just over 11 wks now and although i am over the moon to be growing our little one - everything else in life is turning a very dull shade of grey.
Has anyone been through this and have any advice to perk up? I dont want my better half to find out incase he thinks im sad about the preganacy... and its effecting my job now :-( Or maybe im just overly tierd and sick like every other lady out there and should suck it up??
Any comments welcome
