Thank You Natsy. I think that's the really difficult thing - feeling like everyone else is wallowing in Motherhood, and loving every second, while I flail around trying to figure it all out. Seeing your words there "You're definitely not the only person to feel like this" makes the world of difference.
Also I think, when I do have a fab day with DD, and realise that she is worth all the saggy tums etc in the world, I then start to beat myself up about the times I cried, or the times I missed my "old" life. Does that make any sense? I need to address that. I spoke to DP on the phone last night, and for the first time ever I talked about PND to him, and how I need to address it. Just admitting that to him felt like a big step. I think we have both known, but it's always been a bit like the elephant in the room IYSWIM?
On the plus side, I have had a very positive weekend. One of my pre-beby friends lives on the island. I don't see her that much since I had DD, but last night her and her DP, who I've also known for 8 years turned up on my doorstep with a couple of bottles of wine and a Birthday cake. We made dinner together, and after DD went to bed we drank wine ate cake, and just chatted into the night. Then this morning we all met for brunch. Definately good for the soul.
DD has been a little star today, and instead of feeling terrible for all the times I've let life pass me by in the last 17 months, I tried really hard to just enjoy the day and not feel bad for the ones that have gone before.
DP and I both have a day off tomorrow for my Birthday - I think we will take DD to her morning session in nursery, so we can have a bit of time as penguins and Mrpenguins, and not just Mum & Dad, and then we'll pick DD up early and have a bit of family time.
I still feel guilty when I have a good day. I also feel scared. Scared of the next bad day, and scared that having a good day will make the next bad day worse...IYSWIM. I realise that might sound a bit like I'm rambling, but it's been such a relief to finally get all of these thoughts and feelings down. Since I wrote that OP the sense of relief has been massive. I hope it will be Ok to keep posting on here while I continue down this path. Thank You SO much to everyone who has posted.
