OP you are being WAY too hard on yourself. You sound depressed to me. I say that because I have felt exactly as you feel, almost word for word, and I was depressed at the time.
I think it could helpto go to the GP and explain how you feel. The right medicationm might give you the lift you need.
If not, try the 5-minute rule.
You can do anything for five minutes, so only do things that take 5 minutes.
- Quick cook pasta and a jar of sauce - 5 minutes dinner.
- Or chicken pieces in a roasting pan with baby potatoes and chopped carrots, a sprinkling of herbs or spice and 1/2 cup of water - takes 45 mins to cook but only 5 mins to prep.
- Fish fingers, oven chips and peas - 5 mins prep.
Look up 5 minute HIIT and 5 minute yoga stretches on You tube. Do those for now.
Use Flylady 5 minute room rescue. Hang up coats and bags, pair shoes, fluff cushions. Or empty the bin and wipe the kitchen surfaces. Get DC to help.
Chat with your DC. Tell them you;'e been thinking life would be easier and less stressful for every one if you had some routines. Ask what they think would make a good routine. They might have great ideas. You really don't have to be the boss of everything and everyone all the time. That is a really recent, rubbish trend in parenting and I fell into its trap. It is way better to get them to be self-reliant. Help them create and stick to their own routines: sorting their bags out for school next day before they watch TV. Choosing food from each food group: 5 a day; protein, complex carbs etc. Youy could have a family Lazy Day once a week where you eat ceral and stay in PJs. But the rest of the time, encourage them to take care of themselves.
