Oh dear, virtual hugs and chocolate cake all round. Sounds as though everyone's got some hard stuff to deal with at the moment.
Kate I feel especially sorry for you and FWIW it all makes total sense that you feel like this - after a period of coping with everything I think the pressure has to come out eventually. You've not only had these 6 weeks of getting used to the peg (and that's extra stress that no mum of multiples needs to fit into her day) but a long period before that of Emme being quite seriously ill, with all the strain that that brings into a household, and now an open-ended stretch ahead of uncertainty and non-normality. Sorry if that just rehearses the reasons why you felt down, but my point is to show that you've had a tonne of hard things to do on top of just running a household, being a mum of 5 etc etc. Many, many people could not do "the basics" of your life without huge amounts of help (or couldn't do it full stop), and you have extra portions on top.
So there's nothing wrong with feeling blue. I wonder if Tamba have some support for you and in particular might have some tips on how to manage the differences between your children without having to feel that you are a cheerleader for feeding tubes? Or perhaps on here there is a forum that can help. I can only imagine how difficult it is trying to make sure everyone feels OK about it while also getting to grips with what it means for Emme's long term health and your family life. Chesti very rightly said you mustn't feel bad about offloading on here. Maybe at the moment you should do a lot of it to help sort these thoughts through in your mind.
And Lottie I really sympathise on your night out. So sorry that the holiday isn't very relaxing so far but I think there's a lot of truth in the idea that holidays are more for dads than anyone else! For mums, it's just all the same stuff as normal to fit in, while in a less convenient, familiar and well set-up environment! I haven't found our holidays at all relaxing so far, though have appreciated a change of scene a bit. Mostly I just find myself thinking everything is less efficient than it would be at home what a tedious robot I am.
I reckon some time off from the girls would do you the power of good, and maybe someone else would knock the odd corner off them too. Do explore the idea of nursery, it sounds like a great idea to buy you all space apart and maybe make you glad to see them again!
Will try to get back on here later but better go and make sure I've got my shit together for the day. Just wanted to say something to you both as my heart was going out to you both last night catching up on things!
