I know it’s easier said than done with all you’ve got going on. I’m lucky that I have the freedom to take an afternoon to myself these days.
I think it’s about doing what’s realistic at any given time- it could be mindfully drinking tea or positioning yourself in the sun for a few minutes.
When I was having a tough time post break-up I wrote myself a list of self care ideas to remind myself when I really didn’t feel like I could do anything. It included very simple things like 3 deep breaths, look at the sky, make yourself a cup of tea etc. Sounds silly but it helped me remember that I was worth looking after.
Please don’t beat yourself up about parenting- we all just do the best we can with the resources we have through different phases. The last thing you need is a message to yourself that you’re falling short in some way.
I agree at the protection practices along with whatever self nurturing you can manage being a good idea.
I like salt cleansing and smudging to clear negative energy from a place, followed by filling the space with new, positive energy- burning oils, a piece of nature brought indoors- anything that gives you a message of hope.
I think sometimes the best we can do is put one foot in front of the other and tell ourselves we’ve done well to get through the day.
I like speakout’s earlier reflections about nurturing your inner child (I think they’re on this thread) when going through a dark time.
Sending you love and comforting energy 
Here’s the bedding I bought today if you fancy some window shopping ahead of your move! (Although it’d be great to do something nurturing for yourself for now too!)
