I am sorry that your husband is not supportive -- neither was mine. Not at ALL.. don't let that stop you. It's not HIm you are doing this for, it's YOU.
My husband was so disgusted with my having the surgery he didnt' want ANYTHING to do with it, I had to go through it all without him, and on my own.
I am all alone here, far from homoe.. have no family but him so I hired a "Medical Escort" to take me home from the Endoscopy, and then the Surgery waiting time, with instructions to call my aunt if anything happend, and finally to bring me to the train to ride home when I was released from the hospital.
So... if you are committed to doing this for YOU, without any support, on your own. go for it. Join your doctor's support group. Talk to people on this forum and ask for help.. don't let fear of disapproval keep you from your dream.
AND I AM NOT SORRY!! HA HA HA... now he compliments me and we never talk about those "bad days."
It's not easy, but you are worth it. BE STRONG, be your own best friend.
