i am pregnant with baby no.3 and have been feeling really depressed for the last 5 -6 weeks,have just told the midwife about it and she advised me to see the doctor as i new she would.i had pnd after both the boys but never in pregnancy,i havent slept for about 6 weeks and go for days without eating then eat everything in sight for a few days and the pattern goes on. i have recently split with dp but this is not the cause of the depreesion as i had it before the split.i feel such a fraud as i should be happy to be with child but i just feel really lousy and lethargic and cant get motivated to do anything,everything is such a huge effort.i havent gone to the docs yet as i know there's not much that can done while im pregnant and i worry that to hear that will make me feel ten times worse.everday i get up hoping i will feel better but it just doesn't seem to be going away,please help.
