Hi Marsha
I was older than you at 45 when I was diagnosed and decided to have my ovaries removed in August '06 purely as a preventative measure as I'm highly triple positive, my onc agreed there was good reason to do so and felt ovarian and breast cancer are so closely linked it would cut my overall risks.
The surgery was no big deal at all and i was just a little sore for a day or two. I had no crazy mood swings at all, I did get some heavy hot flashes for a month or so but these began to diminish after that.
I've had no problems other than some bone/joint pain and stiffness from arimidex although my last dexa scan did show some bone loss which I now take fosamax for. It's a tough decision so research it well and go forward knowing you did the right thing for YOU!
Good luck
