I have thought of little else since I read your post last night
I have name changed for this
We are in very similar situations. Or rather we were until about a month ago.
I’m 37. 2 children. Just under 17 BMI Also a runner. Also prone to evening cereal binges.
All going well. Or so I thought. Then the following happened
Periods stopped
Hair fell out
Began to feel dreadful
Flat and sad
Started to look fu@king awful - haggard, gaunt, aware of people looking at me (I have gone the duration of summer hiding my legs and arms)
Blood tests revealed hormones all over the place. And Doc and encronologist agreee likely due to under eating grossly and over exercising.
I had a bone scan. I am at risk of osteoporosis. The hormone imbalance was making me feel so foggy and flat
But I kidded myself that all ok because I do eat, 3 meals a day. Just extraordinarily healthy. Fruit for breakfast. Salad and chicken breast and more fruit for lunch. Huge pile of steamed veg, more fruit and yoghurt for dinner. No fat but I certainly wasn’t starving.
I was kidding myself.
What’s changed.
I went on the HRT oestrogen patch to deal with my bone risk and also my low mood due to low oestrogen. I feel like a different woman. No fog, no flatness.
This enabled me to see the truth. I am reducing my life span (and my looks!) by depriving myself.
So in the last month I have done the following.
Reduced length of run to 10k maximum and no more than 4times a week
No cardio classes at gym. Just yoga/Pilates and body pump
I have salmon or half avocado every lunch time without fail (big deal for me as fat was my nemesis)
I am seeing a therapist once a week
I have incorporated an evening treat before I go to bed of a bowl of Greek yoghurt mixed with a huge handful of nutty muesli (again buts were my nemesis).
Baby steps BUT I have gained 3 pounds and damn it I’m not losing them.
OP. We are too old for this. That was my epiphany . We have children who need us, now, tomorrow and in the future. I want to be here for them, not as a shell of a person but as a fully functioning woman.
Good luck OP
