Tough call, he/she may want to up your pred in take. I've heard people on up to 60mg of pred to control their symptoms (bleeding). I havent yet tried rectal meds so i can't really speak to that.
Other then that, I feel your pain with stress. My job is very stressful and sometimes almost blame my flare since diagnosis because of it.
Take it easy and listen to your GI (if he/she is good).
Good Luck!
