Hang in there. It will get easier if you can get the flare under control. Prednisone makes me insane! I am on it now, for the second time since my diagnosis. The first time it was for 7 months! I didn't recognize the side effects for what they were at the time. Now I am really tuned into them. I am like "justwrong" on it, one minute happy, then I am crying, then I am in a rage for no apparent reason.
I have been on Pentasa for over a year now, 4 pills twice daily (4 grams total daily) plus Salofalk (500mg suppository). I firmly believe that the Pentasa is what helped me so much last year. Up until then I was only on supps as I had originally been diagnosed with UP. Then last year when I was diagnoses with Left sided colitis, I was put on the oral Pentasa.
As for diet, if I am in a flare, I eat refined foods. I know it is hard to accept when we know it is bad for us but you have to let your guts rest a bit. I eat white bread, white rice, white pasta, avoid raw fruits and vegetables and try to eat smaller more frequent meals. I can tolerate dairy and meat just fine as long as it isn't huge quantities. I avoid alchohol completely when in a flare. But just because it works for me does not mean it will work for you. Trial and error...........hope and faith.........
Good luck.
