I don't know.
It is certainly something that happened to me when I came off the pill 4 years ago and started my menopause journey proper. I couldn't be arsed and didn't care about it that much either

I had an op and just didn't seem to be able to recover.
I started taking vit D and got some enthusiasm together to want to do things that I couldn't be arsed to carry through - so a huge improvement

Now I am wondering why I want to be doing those things anyway - I have always found life to be a bit uphill and things have not turned out how I hoped, that I have not control over, so I am a bit lost - lots of things going on (or not, in actuality

)
