I hope you can get a relaxing day or two when you get home PR 
Good news Persepolis. It's a shame you have that stress when I'm sure you would rather be delighting in your pregnancy. I love that secret stage at the beginning when not many people know.
GT I felt the same when I went back to work after DS2 was born. It seemed that I was getting the kids ready for nursery, going to work, going home and putting them to bed. It just didn't seem worth it, even to be earning money. I cut my hours from 40 to 35 a week which gave me a bit more time each day with the kids. Would you have any options for reduced hours or part time work? You seem to be beset from all sides at the moment and I do think you need to try and prioritise your needs a little more so that you don't get bogged down in the daily grind.
I wonder how Kyz and E are doing? I hope he's back to his old self now.
