Thank you so much for all the comments and emails, it helps more than you know.
If we could just get the car situation sorted, we'd both feel so much better. At the moment we're getting nowhere. And that's all I'm saying about it.
We're off to the caravan again on Friday, no firm plans for when we'll come back. I know several other van neighbours are planning on being there, so it'll be quite a reunion I should think. And the weather is forecast to be much better.
On a good note, my knee is (fingers crossed and touch wood) not so painful now, I've not worn the support brace thing for 2 days and the knee hasn't collapsed once. So maybe it was ligament, tendon or muscle damage and is now hopefully getting better.
I'm spending a couple of days doing some more batch cooking and baking before we go to the caravan, yesterday I made 3 fish pies, all now frozen. Also got dog food to do today.
Physically I'm fine, albeit suffering greatly from lack of sleep, but I do feel very flat and emotionless right now, as if I'm operating on autopilot. I'm sure I'll pick up once we're back at the caravan. Thank you all once again, it's so nice to have people get in touch who actually care.
