I think that you are really fortunate that you were in the hospital when it ruptured. The fact that your colon busted really supports the fact that you have been really sick so I bet you are glad that it is over. I had surgery almost 4 months ago. Although my surgery was elective, my surgeon told me that my colon was like tissue paper so that confirmed to me that I was glad that I did it. I was pretty sick before the surgery. I have found the recovery pretty easy. I was able to go back to work within 30 days (although it was not easy, I was able to do it). The ostomy is certainly weird but I have adjusted much better than what I ever thought I would. I don't "like" it but I do like not feeling so sick anymore. Like you, I ended up in the hospital too much with colitis so I am thankful that is over. As for your weight? I lost a good amount of weight with colitis but now that I can eat what I want.....I am gaining weight that I wish I wasn't so I am confident that you too will get your appetite and re-gain atleast some of your weight back. I believe that everything is looking up for you know that the burden of having a sick colon is gone. You may miss your colon but somehow feeling healthy eventually outweighs that loss of your colon.
You are doing great so just keep up the good work
