Try to move back to your place. It will affect your mental health gradually.
I’d approach them with how you’re feeling (gently) and let them know that it’s been the opposite of helpful in some ways. Obviously start by thanking them and see if anything changes in a week or month. Let them know you would be fine alone if this is what you’re trading. I personally wouldn’t expect any residents to NOT cook, including you. Maybe they feel like that’s your exchange for rent or something? Either way I agree with Lele. Your child is your priority now, and you have to be sane to care for child.
Remove anyone that is not allowing you to be 100% for yourself and your children even if it is family keeping your distance so that your sanity is intact is not a crime and often we put all this guilt onto ourselves because we know that’s what we should dobut if your family is not helping you out and not making you feel like you have a village, then it’s time for you to create your own with people who are actually putting an effort for you and your children
