Do something nice for her give her a break take the bus for a week and help her with the chores and work and just give her space and if she needs help say that you'll both be there if anything goes wrong.
she shouldn't even make you thinking about and even post your worries!! it's mom, moms are cool and you are old enough to order food. but maybe@she should just take a few deep breaths.
then workout. try not to feel bad, kay hun? 💕🌸
she just needs to hav a few days to hang out and relax wit her kids. There's no need to go out somewhere just stay home play some video games watch a movie. That'll make her less stress and more relaxed
