Hi Sunflower, Agree with pp, go to your GP or practice nurse and explain how exhausted you feel. Ask them to check, iron levels, thyroid, and vit D. All can make you feel exhausted.
I used to set aside a Friday evening for me. No cooking, homework, housework. Kids in bed promptly and then it was my time. Bubbly warm bath, soothing music, glass of wine, a film. Home manicure, pedicure, nice moisturiser, early night.
By Saturday morning I felt human again.
And have a stern chat with your 17yo. You are a team. Don’t feel guilty. If she wants you to cook & clean & ferry her around, she can babysit for 3 hours a week. It won’t do her any harm. x
