I used to feel like this but I've started getting more organised which has helped.
Re uniform we have 2 dedicated school uniform / work uniform baskets. One for white one for darks. DC and DH know all uniform goes in there each night
Fri evening all lunch bags go in the washing machine (wiped also in the week) so they are done. Also make sure we read any news from school and make sure we know what's on the following week of different from usual eg different pe kit etc.
Also Fri night first of 3 uniform washes goes on. I do 1 white and 2 dark. So one of Fri night then first thing sat morning either hung to dry or straight in tumble dryer. If hung to dry I finish in tumbler so no ironing. Sat morning next load in washer and again either hung or tumbled. Both those loads will be away sat teatime. We also have dedicated uniform and work clothes wardrobes.
Sat afternoon we tend to go out for a few hours eg swimming, nature reserve, see family etc.
Sun morning strip beds. Do last uniform wash and dry and put away. Get bags ready, polish shoes etc.
Sun afternoon either out again or a nice activities eg baking.
Sun evening nice dinner, and we want everything ready to go for the next day by DC bedtime.
Sounds like a military operation 😂 but 6 of us here so organisation is key! It took a few years to get into this routine but it's working well
