OVARIES OFF / OOPHORECTOMY

I have a very difficult situation here. I am 41 this year. I was diagnosed with breast cancer end of 2013. I was 38 then. I was very blessed to have found the cancer early. It was stage 1 (I was told), grade 2, HER2 +. Because of my age (being young) and the risks involved, I underwent chemotherapy, radiotherapy, and herceptin. I am now taking tamoxifen (2.5 years now, and was told I had to take it for 10 years), and also zalodex injection each month.

I had a vagina bleeding last year and found that I had a polyp and it was removed then. I was informed it could be because of tamoxifen. I had another bleeding this year and found another polyp. I will be removing the polyps this Thursday. Apart from that, a cyst was found on my left ovary. After seeing the gyne, I was informed that I can remove the cyst by taking off 1 ovary. One thing lead to another, I decided to have 2 ovaries removed instead as it makes sense to remove both during the key-hole-surgery. My thought is I will complete my zalodex treatment when I am 44 years old and my period may come back and my ovaries start working again as I would not reach menopause age yet.

My questions are :

1. Has anyone been through the situation I have been through or similar and have decided to go ahead with removing both ovaries ? If yes, how are you coping with having both ovaries removed ? Are there very bad side effects ?
2. After the removal of my ovaries, do I still take tamoxifen or do I change medication ? If I change medication, do I have to change it immediately after the removal of the ovaries or can it wait ? How is the transition period like and what is done in the process of the medicine change ? I am in a panic state here as the gyne and onko are separate and I have only realised today that the medications has to be aligned to the state of my ovaries.
3. I am worried about the long term effect of the removal of my ovaries. I read it may cause much complications in the long run. Ex - heart attack, cognitive impairment, parkinson decease. I wonder if anyone here has had years of experience in the removal of their ovaries to comment on this ? Or do you have any other findings, etc on the regards ?
4. Please could anyone share anything at all on the above situation, etc ?

I must be honest to say I am having cold feet as we speak as, would really appreciate hearing from anyone at all on all regards.

Thank you.
