Adult ADHD coping and life

[Sxxyfing]

Hi
Was diagnosed at 15, took medication for a year but never again. Now 33 with an 18 month old and finding life getting ontop of me.
I've done well so far with becoming very organised and having diaries, planners, whiteboards, lists, spreadsheets, to keep ontop of things but recently I'm starting to feel overwhelmed, inadequate at life and just can't seem to get myself into gear to get all the things I need to do done.
I'm working part time and finding all the food prep for myself and my little one overwhelming, getting out to do the things that need to be done like food shopping, seeing friends and family, keeping ontop of all the stuff I need for things like Christmas coming up. I feel like by the time I'm up and dressed and the house is sorted the day is almost done and the 3 days I work are just a complete loss as i can't do anything except work and eat and sleep and sort out the baby on those days.
I really want an organised method to get myself back on track. I know it sounds weird but I'd love a weekly/monthly/yearly plan that just keeps me ontop of it all.
Hope this makes sense to someone

It does

Decide on a plan that works for you

eg meal plan on Friday, shop delivered on stat, do some cooking prep on Sunday

cleaning - make a weekly plan that works for your house, decide on a plan for deep clean (eg monthly, seasonal, 2 x year)

Social life - I try to have at least 1-2 things to do each weekend 3-4 weeks out. Can you try to make some 'standing' plans with close friends/family (eg dinner every 2nd week or something so you don't have to think about it too much

I get like this when I am tired/feeling low - do you have any holiday time coming up/can you take any?

Thanks so much for replying.
I have just had stomach flu so the whole week has been thrown out and all my plans have been cancelled which will now have to be rearranged in the future which i think is why I'm feeling overwhelmed more than usual.
I feel like I have so much going on that I'm constantly making plans with people, I wish more regular plans were a thing but i feel like there's too much for me to be able to fit it all in that way.
I definately like your idea of more structure. I used to do a workout and diet plan and I made everything else work around that so no reason why I can't be regimented with the cleaning and food tasks too.
It's hard seeing friends who are at the same life stage just flourishing whilst I feel like I'm drowning.
