Hi ! My name is Amie. My situation was similar - I had an emergency c-section when I was in my early 30's because of a mass that was found. I had a hysterectomy, but I kept "the girls" ( my ovaries).
Afterwards, my sex life resumed once I healed. I actually enjoyed it more because it took unwanted pregnancy off the table. I had already had my two kids.
Within about a year, I experienced early menopause. But I felt that one day it was inevitable anyway, so I just rode the waves. The night sweats weren't just at night time, though I did have to change clothes at night sometimes because I didn't like laying there wet. I remember being at work and feel the wave of sweat coming on, or being at events and becoming drenched. It wasn't fun, but you find ways to adapt. Like going into a restroom and drying off. I just kept telling myself that it was going to happen eventually.
What was harder was going from my normal self to "bitch" in what felt like 3.2 seconds. Thank Goodness for Prozac and other forms of medication. Don't be afraid to ask your doctor for help. There are meds out there that will help. If one doesn't work for you,ask to change to something else.
Hang in there !! It's scary, because it's an unknown. But, it will get back to being "normal" in time.
Take care !!
