I order food deliveries but tend to do 4/5 days at a time rather than a full week. This reduces the overwhelming task of meal planning, means things last until the next shop, and means that I do fewer top ups (in theory)
I have a big list of jobs that are non essential but do need doing, every week I pick a couple, and do those. I accept that this means the list will never be done, but I have so many house/aesthetic kind of jobs to do and I like to feel like I'm chipping away at them. This week it was to frame 2 postcards. It's been in my list since one of the frames broke, oooooh, a year ago.
I lower my standards massively about cleaning. I will whizz round quickly for an hour after work a few days a week and I do a bigger clean at the weekend. We can't afford a cleaner or a gardener.
I schedule exercise and self care every day. The exercise I manage. The self care not so much, but when I'm feeling really overwhelmed I know I need to prioritise it.
Last week when ds was at football, I sat in the car for 20 minutes and did a whole load of life admin- paid school lunches, added all the school dates to my diary, responded to loads of party invites and other stuff, wrote a list of jobs, etc etc. I did so much in that 20 mins! I am going to do that every few weeks I think, it was such a good use of my time.
