HI - It does sound like perimenopause. Not everyone gets all the symptoms. The stress you're feeling and sensitivity to noise can be related. It also sounds like your periods are starting to change. Remember that going 12 months in a row without a period is menopause - you could be in the peri state and just need to get your hormones balanced.

Have you had your thyroid checked?

Hi there,
Well we're about the same age, and I have exactly the same symptoms,especially with noise, and feeling stressed out. I feel like I am going mad.. periods arrive without fail..but definetly think it's a perimenopause. Trouble is that you can feel as though it's just you, and it's interesting to read about other's similar experiences/feelings...just all very stressful, role on the menopause, so hopefully a sense of normality will return...is it that simple though? - Good luck, you are not on your on.
Just to say that I find herbal remedies such as lemon balm and vervain helpful, but there is much more to try.
All the best!
