Yes. It will help. I eventually went to my GP for help and more or less demanded that I was put on HRT when I was about 46 (I think), though in retrospect I think my hormone levels had been dropping for a few years before that (benefit of hindsight and all of that).
I was in a constant state of RAGE until I went on HRT. Honestly, I couldn't have given any of my family a script to follow that wouldn't have made me just want to bellow with anger and frustration, no matter what. I was also having periods still, though not quite as regular as clockwork as before.
Would also recommend that you get your vitamin D levels checked out. I went on HRT and also I upped my own bit D intake (by spray, great stuff), and I felt more or less human again within weeks. Plus the sleeping issues, memory, aching joints etc. All much improved (though the memory not as much as I would like...).
Go to your GP, go armed with your symptoms, get your bloods done by all means, but if possible, see if you can come away from your appt with a prescription (oestrogen gel or patch + progesterone if you do not have a mirena coil) and a referral to your local menopause clinic. Good luck!
