Hello - goodness you really have got yourself down in the dumps, understandably! Welcome to the world of the lopsided woman, the one that feels insecure, feels like everyone is staring at her, and they're not! Please don't make yourself feel bad for feeling like you do, it is ok! We tend to reflect and think what the, how did this happen but eventually we come to an acceptance and look for that new kind of normal.
I've had a left breast mastectomy and I made sure that my husband saw the injury straight away and in time encouraged him to rub in the moisturiser (finally settled on QV cream) into the breast - now I'm better I've decided that is my job not his! It is all part of the acceptance process for both of you. My journey was immediate reconstruction and changeover surgery was 5 months after mastectomy. We are all different in how our bodies react and the treatments that we're all on.
Menopause - not sure who invented it but it can be testing! As Kath had suggested perhaps a natter with your breast care nurse or your local GP will help - maybe you need a supplement to help you through or in a discussion thread recently we all agreed that putting your leg out of bed and singing the hokey pokey helps! Yes I'm on Tamoxifen for 10 years although the Oncologist did suggest he would review that at the 2 year mark and perhaps put me on Arimidex! Side effects are the normal you just need to find a way to cope, sometimes a little thing like changing the time of day you take the Tamoxifen can help!
Not sure where you are, Victoria or interstate. There are lots of good groups out there where you can meet with like minded people as well as us here on the forum that will help you through and let you cry or laugh or anything in between without judgment.
