Not a woman, but I have recently gone through some major surgeries. in 2012 I had a kidney transplant and then a more invasive surgery to fix some structural problems with the new kidney.
It is 2 1/2 years later and things are going well, but not perfectly.
I totally understand your fears. The transplant was my first major surgery and I was very scared. Additionally, there were many issues to be dealt with after and forever regarding medication and other health issues.
The best advice I can give is to try to keep a smile on your face and be kind to your caregivers. It helps a lot! They appreciate it and you will feel better trying to focus on the positive.
Have faith in the people giving you care and in whatever higher power you believe in.
You will learn through this process that you have much more strength than you think.
Good luck on the journey!
