Hi there ~
I understand your concerns and I believe after reading your brief history that getting a hysterectomy
would be a good choice for you. I am glad that you are consulting a psychiatrist
for your mental health issues and I believe they will get better after the surgery, as that would be one big thing to worry about less. About the ovaries, it is upto you to keep them, since your oestrogens and progesterones are produced by the ovaries and you might experience premature menopausal symptoms if you decide to have them removed. However you should consult your gynecologist who will perform your hysterectomy about this.
Take care of yourself and have a lovely day!
