I'm 43 and work in a high pressure job where I have to be constantly on the ball and thinking 2 steps ahead. Been suffering a slow brain and increased anxiety as well as fatigue, and very worried that I can't continue in my current career like this! Pretty sure its perimenopause as Ive also started getting heavier periods, a shorter cycle, dry skin and thinner hair. Made some smaller errors at work so far and feel generally a bit useless, but feel its inevitable i will make a more serious one that i can't fix at some point. Anyone else had similar? Or changed career/downgraded job due to this?
