Declutter your entire house, go completely minimal, Marie Kondo the sjit out of everything. This way you can clean a whole house in minutes.
I buy antibacterial cleaning wipes and floor wipes and use them in between proper cleans to keep everything clean and sanitised.
Look at the organised mum method. Assign everyone jobs and attach pocket money (if you give) accordingly.
Go minimal with cooking. Easy, quick and healthy: salmon fillets in oven with asparagus and microwavable rice. Done in about 2 minutes prep, wash and sprinkle olive oil and sea salt, bake for 15-20 minutes. Done and trust me absolutely delicious. Can give you more meal ideas like that if interested.
Uniform:one set per day, so no stress and go for non iron stuff. Outsource ironing to a local person in need for money.
Online supermarket shopping for food. Once you have shopped 1-2 you will find it very easy to do, as you can pick your favourites and add them to your basket. Ocado are great for new customers as they offer free delivery and money off.
Stop all after school activities if possible. In my opinion, kids are doing way too much and need down time. Also ditto for weekends. Unless it's something that they are really keen on and enjoy, no need to be packing things in and drive yourself crazy managing them. Share lifts with other parents to give each other a break if they choose to continue anything.
For physio, my therapist comes at home (but I pay privately). Would that be an option for you?
Husband needs to be an equal, if you need to micromanage him to begin with so be it. But for the love of God don't be a martyr. Get him to do his fair share. Kids too. You are a family unit. Sharing is caring and all that.
Pre plan and diarise activities for you to get some down time. You need a break. Also discuss with work possibility of working from home some hours/days if at all possible.
Up your vitamins and supplements in case you are deficient and your fatigue is a result of that.
