Hi Pumble, just saw you bounce to the top of Threads I'm On so I thought I'd pop in. Especially as last time I posted I said I was going to put the virtual kettle on for you, and that was Wednesday... 
Sounds like the rollercoaster is beginning to slow down a little for you now. If you have a spell of thinking 'this is awful, I'm getting nowhere' just have a quick look (if you can bear to) at the early pages of this.
That Pumble was an exhausted miserable mess.
Current Pumble is much chirpier and much more rational. She still has shitty moments, but they're much more like normal shitty moments that we all get when the children have the snots and you've done as much playing outside in the snow as you and your supply of dry socks and trousers and gloves can take and everyone's got cabin fever.
The feelings aren't fake. They're the feelings that Pumble ought to have been having if her hormones, or whatever it is causes PND (sorry don't know what causes it, just know it's horrible but fixable), hadn't been making her life merry hell.
Sorry, waffling on a bit, but the jist is you're fantastic, you're doing well, yes there's still a lot of progress to be made but you're making it.
PS I once told dd1 that I was going to put her in Baby Prison if she didn't shut up, and I bloody well meant it at the time.
