I lost my colon and rectum due to a different reason than yours. This was 7 years ago and I did feel like a freak at times. I had a couple of friends get weird when I told them about my impending surgery. Guess what, they are not my friends any longer. I guess they couldn't handle the fact I lost MY colon. Once I got my life back (too sick with a colon) and began doing all those things I couldn't do with my colon I lost the freak label. People I have met since I had surgery don't know that I am different than there are. I don't bring it up unless the conversation warrants it. I am not embarrassed but I have always been more reserved. The way I look at it is that you are giving your body the opportunity for better health. If it takes a radical surgical procedure, so be it.
Most people don't know that the large intestine is an "optional" organ. I didn't know until I was told that I had to have mine removed. That's when I found out that the small intestine absorbs nutrients, and the large intestine extracts fluid, so you will not be missing out on vital nutrients after having surgery.
Are you going to have an ostomy or will they connect your small intestine to your rectum? I'm glad that your family is supportive and that you found us here, because we understand why you're having the surgery and that your life is going to improve dramatically afterward.
