Your mind and body are calling out for gentle self care, being harder on yourself is just going to be like kicking yourself whilst you're down on the floor
you're dealing with alot, whenever you can be kind to yourself. Think of self care - it will all help towards your healing, do your best to eat as well as you can - think veg and fruit, fuel your body as best as you can during this stress. On days it feels too hard, add a shop bought smoothie or something easy like that
See if there is any very gentle movements you can try - look into tai chi perhaps if you feel at all able. When you can, stop and rest - do something nice for yourself, paint your nails, soak in the bath, watch a film, read a book, make a den with your daughter and rest in it together - anything you can think of to give your mind a rest from the current worries just for a bit All those little acts add up. If it helps write down all those little achievements of self care - acknowledge your progress (on a really hard day, just getting dressed or having a shower can be a big positive step)
You can do this, break it all down into little steps.
Just like a tall staircase you only go up it by taking one step at a time. Some days it will feel overwhelming and those days be gentle with yourself.
