How can I tackle my REALLY bad allergies?

I am constantly from day to day held back because of my allergies. I am allergic to grass, trees, bees, dust, mold, cats, dogs, nuts, peas, green beans, soy, wheat, cigarettes, and down comforters. As you can tell I have already been to an allergist and gotten tested. Through my course of going to the allergist, I have about 4 or 5 medicines daily and constantly have to take multiple benadryl a day and that doesn't even help. I also have dry, watery, itchy eyes that get so bad that I have puss and almost blistery looking bubbles on the outside corners of my eyes. I have tried EVERYTHING. I have hypo-allergenic pillows on my hypo-allergenic bed. I put cold wash cloths over my eyes, I take a shower before I go to bed, and still NOTHING helps. I am in desperate need for SOMETHING to work!! PLEASE help!!
