Your pouch is very new-- it takes time to heal, as I'm sure you know. Leakage should stop. My 16 yr old son is in a similar situation. UC didn't respond to meds, hospitalized 2 times for UC, got PICC line for TPN, then 3 more hospitalizations for surgeries- colectomy & ileostomy, emergency bowel obstruction and then J pouch. He got his J pouch June 24. He's entering 11th grade but still getting tutored for 10th. We don't know if he'll be ready for a full course load in Sept. His friends are doing SAT prep, but he has no time for that. We are encouraging him to consider taking a year off after high school to either work, go to community college, or volunteer. I realize it's probably not something you want to do, but I imagine it wouldn't be problem to defer your admittance for a year. In the scheme of things, starting college at 19 instead of 18 isn't the end of the world. Your health is most important. Best of luck to you!
