Oh do I get it. Although I am 56 now, I had my ovaries removed over 10 years ago to shut off the estrogen so I could go on Arimidex which was brand new then. So at 45 (only a bit older than you and 100% premenopausal), I truly, truly understand. But I will say it improves or maybe it improves because you just get used to it. But, in August I will be at 11 years with no recurrence. You can see my signature and I am very similar to you and I am still here. I have 3 daughters and have seen all 3 graduate from high school. 2 graduate from college (one to go) The oldest is 3 years married and another is getting married in September. So, to me all the crap and treatments and menopause is totally worth it and you will see that it will be worth it to you - scratchy vagina and all
Huge hugs to you
