Welcome to HCM,
As you are 43 years, it seems that there is some hormonal
changing going on due to pre menopausal stage giving you all this feeling.
But this is the age when you should go for thoroughly checking of,
2,Blood sugar fasting and PPBS.
If all the reports are normal then nothing to worry, gradually you will be alright.
If your problem persisted consult for gynaec opinion for any hormonal treatment.
Ok and bye.
