elsa sorry you're having a crap day.
Go back to work after maternity if you want to, just explain to dp that you'd prefer to do that. If he's negative about it just explain about when they're both in school you'll be much better off, and its hard to find a job after a big gap etc.
Arm I'm working even though it leaves us no better off but I got so fed up of being on my own with no adult company all day.
As for anti the anti depressants maybe see your gp? As far as I understand some are pretty safe in pregnancy so if that's what you need to do for your health then maybe that's what you need to do?
I stopped mine cold turkey once and it sent me psychotic so be careful and keep an eye on yourself if you can (not saying that will happen of course!)
