Maddymom,
I am 60, and have been in menopause since I was 53. I had a horrible time in perimenopause, and yes, with regualr periods. But the things that you have mentioned, were also just as frustrating and dramatic for me. I know how you're feeling. Trust me, I do. It's scary, isn't it? Crazy how our life changes with this transition. So to your question about 10 years of periods and crazy symtoms, I don't think so. On average, you're a little to old to be having periods for the next ten years. The average age of menopause is 52.
Now in my situation, I did see some differences with my periods at age 43. Lighter flow, sometimes clots, sometimes heavy stretchy mucus in the second half of the cycle. And then a shortening of the overall cycles. I had been like clockwork my entire adult life. And I did, at the time, try several hormonal options. I was put on a birth control pill and it was a total disaster. Tried to use bioidenticals for two years, and that also was horrid. So, eventually I went back to using nothing. Over time I leveled out, and felt like my more normal self. I had periods for the next 8 years, which slowly tapered off. (But then I was younger than you are right now.) First it was a period every two months, then three, and then finally one every six months. Then they finally stopped. Oddly, I breezed through meno as though it was nothing. No hot flashes, no night sweats, etc. All those wonderful things, happened in perimenopause for me.
But I will also mention, that menopause is not something that is "you have it and then you are done with it." Nope, because our sex hormones interact with every other hormone system in the body. So when we lose them, our other hormone systems change as well. This is really a life transition. Where our entire being is evolving and changing. And it continues to change.
Stinks, doesn't it? Because i think if we had a choice in all this, we'd all pick staying about 40, with things running pretty smoothly.
Sorry you are there right now, with all the changes I mean. But it happens to all of us. What you might do, is try to be very good to yourself. Get to bed earlier and get some good sleep, eat well, drink good clean water, take a good mulit vitamin, exercise a little (don't over do it), take time everyday to focus on something you want to do just for yourself. Anything you can do to help your body ease into this will be a benefit.
I can't tell you how much I wish, I was the "ME" that used to be. (And don't get me started on that wonderful vaginal atrophy and dryness. Cause that's a real kick in the gut.)
