Hi again inthedumps. Are you sure about moving? I lived in London and then moved to Devon and after 3 years moved back to a city. I was going to post something like 'oh, I felt very like you do, cried a lot, mourned my old life, etc and it's a perfectly normal reaction to new parenthood and then I remembered that I WAS depressed after having ds! I went to my GP who suggested St Johns Wort, which I took, and eventually I got better. But I have read somewhere that some pnd is a perfectly understandable reaction to new parenthood and I can go with that. I think it was hard, for me, to accept that it wasn't just me any more, that someone else relied on me totally. It's hard even to get time to think sometimes isn't it?
Can you just hold fire on moving for a little bit, say a couple of weeks? Because it might create more problems than it'll solve. Tbh, one of the, not sure I'd call it a symptom, but anyway, one of the things I kept saying about a year after my ds was born was "I HAVE to get out of London, I just have to" and I didn't realise it then but it wasn't really London, I was just blaming that, it was my new life/parenthood/my marriage at the time (we're amicably divorced now!) and I was looking for something to blame so London was it.
Anyway, I think IF the main reason for moving was because your parents offered to help then pause, don't do it yet, really. If there were other things then maybe you should still go. My experience of Devon is that it can be very small town and lonely and isolating and I wonder if it might not be the best place for you right now.
I also know what it's like to be disappointed by your parents and to want them to do more than they do: when I had ds my mum went and adopted a baby of her own so was no help whatsoever as she was in the same boat as me. But you can't change parents into what you want them to be, I'm trying to accept that now.
Can your partner have your child while you just take a day out to think and decide what's important to you?
Another thing, if you're knackered it affects everything IMO, you just can't think straight and it's very easy to get everything out of proportion and to find life tough, because it is without sleep. They use sleep deprivation as torture don't forget! So I think you need to sort out the sleeping before you even begin to think about tackling other issues - you will feel a lot better about everything if you get some decent sleep.
You also need some mum friends. I struggled on with my ds for 18 months with NO mum friends and it's only when I look back that I see how isolated and lonely I was really. The days seemed to go on for ever. (he's 8 now! And there was no mumsnet then, more's the pity) Are any of your childless friends capable of looking after your baby for a few hours while you sleep? I know they won't get it fully, but you say some of them were nice and clucky and kind to you, so ask them to help you, they might be more willing to help than your parents.
It's hard getting used to being a parent I think, well, I certainly found it so anyway and you do need to meet some people who know what it's like I think. When I finally got around to going to a playgroup with ds it was wonderful to finally meet some nice people with children.
Anyway, you're not alone, you've found mumsnet and lots of us sympathise and hope we can help.
