This level of stress will make you very unwell, it will suppress your immune system and give you an achy body and slow decline in physiology. On top of that poor sleep and a washing machine mind.
Please detach from your WW and have a short break from your sitch.
Your health needs extreme care and uber nutrition. Please seek some health checks and know your numbers.
WW will do as she does, you have no say in it. The fretting will really drive you into the ground at a time you need to become a partner only a fool would leave.
Letting go does not mean ceasing to stand it means that what WW does no longer drives your emotions.
I wish I could offer you a large drink of your choice and warmth of your friends here on the board.
Big hugs
