How can i reduce allergy symptoms?

my allergies lately have been giving me breathing issues even though i don't have asthma (i've been tested by a professional i definately don't have it} my sinuses is swollen so i can't breathe through my nose that's a contributing factor. I just can't take a good breath. since the end of may 2011 i havent been the same but this past winter and last summer i was breathing normally so i don't usually have this symptom i just hate it it's annoying i'm buying a vaccuum tomorrow cause i have a rug in my room that i cant get rid of my mom won't let me what can i do to avoid allergens that mess up my lungs btw i never smoked cigarettes or weed or anything and i DONT HAVE ASTHMA so why the **** am i having breathing problems? wait i know goddamn allergies ****! i have a life and want to enjoy my summer which just began on june 1rst any advice on this would be greatly appreciated thanks. I'm allergic to dust pollen and mold. I just went to the doctor and she said my lungs are fine i just want to get my breathing back on track so i beg you plaese tell me how to better avoid these pesky allergens thanks god bless you i'm in dire straights rite now
