Lauren, I am sorry you are having such a difficult time with everyone...I don't have an answer for you but I did want to say that you sound like you would be OK with a colostomy and that is the hardest part to come to terms with. I understand not wanting to go through two procedures and as long as you are comfortable with everything (especially the outcome) you should go for it regardless of what others are saying.
Not to sound cold hearted, because you know they love you, but they are not living your life of pain an suffering...and it's probably BECAUSE you are 26 that you want to have this done so you CAN get on with YOUR LIFE
I know you and I have almost identical stories, and I too did trial and error. I do not have a colon, but I am sure you read ended uo with a could have been fatal bowel obstruction and now have a loop ileostomy. The first week foe me was awful. I will not lie, but I had emergency surgery and did nothave the time you have had to plan for it. I feel better, look better, have color, no pain (well except where my abscess and inscision since I am only 10 days post-op) but this is controlled with vicodin as needed. I have n=been in the hospital most of this month and think I may be going home today.....I am doing better with the ileo, but I am still looking into the k-pouch and having a consultation with Dr. Remzi for a continent ileostomy. I am only 28 and the hardest part for me has been my body image with the bag and I want to see if I can help this. I am married and have the most wonderful husband who if I asked would empty my bag!!!! I wish you the best in your decisions.....you just follow your heart.
