Babypink,
We have spoken before re bowels and investigations, and you may not remember but I have said on this forum before that I too have a stoma, an ileostomy, which I have had for 10 years now.
Life does go on,and will be perfectly normal for you once you have got over the initial surgery, and may even be better if the diseased bowel has gone.
Investigations such as colonoscopy can be tricky if your bowel is friable (weak) and perforation is quite a common complication.
Be kind to yourself and accept all offers of help while you recover.
