Severe dustmite and eye allergy

I have Ulcerative Colitis and severe allergies to dustmite and catdander. While the UC is under control, i do believe my allergies attribute to disrupting my digestive system. I took allergy shots for 2 years but had to stop given the UC diagnosis and onset of several flareups. While being on a strict diet for 18 months, my UC is much better but my allergies are killing me. I started sublingual allergy drops a month ago and the docs told me it will take at least 3-4 months for me to see any minor improvement. Meanwhile, I am suffering esp from eye allergy and have been getting frequent allergy conjunctivitis (eyes are heavyset, dry, completely swollen, reddish and itchy with some mucous - even the face swells up with acne breakout and itch - whole face looks very deformed). I wake up exhausted. Other symptoms include extreme sensitivity to cold, itchy throat and ear and sudden bursts of sneeze attacks. Please advise on what to do and let me know if you need additional information.
