Hi, i'm sorry to hear that your recovery has been so rocky emotionally. It's rough to go through the trauma of surgery and then to have the additional problem of the hormone upset. It feels like it will go on forever.
It's possible that your hormones are still finding their level.
After my hysterectomy I had a few episodes where I felt like things were completely out of my control. I knew it was the hormones, that there was no rational explanation for my fear, anger or sadness at any particular moment but it still didn't make those feelings go away.
You might want to check out a group called hystersisters.Com, you'll find lots of other women there who have been where you are now (or have been).
Take care.
