Thank you so much @bellinisurge and @ElyElyOy - that's really helpful.
I hadn't even realised it wasn't a good idea to use a camping stove indoors so I've a lot to learn!
I can make bread to a really simple recipe. It's a bit stodgy, but will experiment in the next couple of months. Forgot to mention the treats - apart from chocolate I've bought a couple of big tins of shortbread and biscuits which were on offer for Christmas, and will keep gradually adding things. Things like that, plus coffee, are certainly comforting to think I have. I don't really drink much alcohol, but was thinking I'd get some supplies as it might be useful.
Someone on these threads had mentioned bin bags before, so I have been making sure we have extra supplies of these. Washing powder/liquid is a good idea, so will add that.
We do probably have enough warm clothes and blankets, but will look at getting some thermals in the sales. We have one oil filled radiator that can be plugged in, but that's it. Gas central heating, and no working fireplace or anything.
I think it's partly the scale and uncertainty that freaks me out. But losing water and power supplies is the big fear for me
I'm sure you already know much more than me about meat replacements @bellini as you've given so much brilliant and reassuring advice on here, but if you like pulses then replacing meat with lentils is a good swap in lots of dishes (chilli, casseroles, bolognese type things)
I'm trying the best I can to manage my anxiety, but Brexit has been massively triggering for me. DH was very dismissive about the idea of a Brexit stash, but has been adding bits and pieces to it over the last few weeks, so it's helpful to know that I'm not alone in trying to prepare. Still can't quite believe we are actually having to do this.
