My timeline is the same as yours pretty much, but three children. I had exactly the same feelings at 36. It’s the female midlife crisis time, the late thirties. I remember my aunt going wild at this age, losing crazy amount of weight etc etc Some people have affairs at this time, too.
I felt like I woke up with a jolt after the fog of the early child rearing years (youngest was three) and saw in the mirror an unrecognisable, fat, middle-aged frump who was def past it. How did it happen in 5 years going from young, beautiful, sexy and smart girl to a fifty-year old look alike? It was a shock. I wanted to run away, break free, get my life and my old self back. And do other crazy stuff.
I blew over in about 12-18 months. So glad I sat on my hands and didn’t do anything I would have come to regret. Suddenly, life doesn’t seem so bad any more. The positive outcome is that it gave me a good kick up the arse to get up and do something about my neglected, out of shape body and made me more assertive as to see to my needs being met, too. I don’t feel guilty leaving my children for a few hours to go to the gym now, don’t feel guilty reading a book instead of doing housework. Or doing nothing and having a break. That’s fine, too. Feel so much better for it.
Pleased to report I no longer look and feel fifty, people have told me I dropped 10 years after I lost 2 stone of weight and rediscovered my confidence. I look and feel attractive again, content with my life. I am glad I didn’t divorce, I am glad I didn’t have an affair, I am glad I didn’t do anything stupid while in the grip of my mid-life crisis, although if was so hard to be sensible at times. It will pass, too. Use it to your advantage and don’t do anything you will regret later 🌹
