Hi Severin, I just read your post that you had to have surgery. Sorry it wasn't so much your choice but I really hope this is the beginning of healthy days ahead. It's great that your doctors feel you will be able to have a j-pouch.
The first few weeks can be tough--recuperating, healing, getting used to the stoma. Enjoy the better moments and just get through the harder ones. It may be two steps forward and one step back at times but it will get better. Bratcat is now 6 weeks post step 1 and physically is doing very well. Back to work part-time, more energy, almost no pains.
Give yourself time to heal. Enjoy no more UC symptoms! Keep us posted on how you are doing and let us know if we can help.
