Big hug to you. I've been through what you're going through and completely understand how you feel.
My disease was also in the lower end of the large intestine and rectum, so you would most likely have the same results that I did from surgery, which has been no more Crohn's. It has been the closest thing to a cure for me, and that's why I log on here every day, to tell people like you that surgery will make your life so much better than the way it is now.
I'm glad you have a loving and supportive man in your life. My husband has been wonderful, too, and was my rock during all the years I was sick. He has also been here to see me healthy after surgery. Going through this bonds you in a special way.
Can you ask your doctor for some medicine to help you get through this emotionally until you're through surgery? Please know that we are all here for you and will support you every step of the way.
