Hi I Have Had A History Of Asthma, Though I

hi i have had a history of asthma, though i smoked less than 3 mos i think in my whole life and that was when i was in teens the first time and early 20s second time, but I have been wheezing when I breathe in and coughing since about 1998, or 99. I have recently had some tests because I have an out of breath feeling when I walk and especially when walking and talking, I have been feeling very tired and maybe it's just depression, but I can sleep along time and it bothers me. I feel tired alot and wheeze alot and just feel so blah. i'm 42 now and I just feel so down about all this. I was around someone who smoked for about more than half of this year. Not constantly, but when he'd take me somewhere, or I went upstairs to his apt. I'm feeling so down. :'( My dr had an ecg, chest xray and pulmonary function test done. 2 were done 2 wks ago tomorrow and one other for lungs was done this fri nov 20 2015. I haven't heard anything. I'm tired of wheezing all the time and inhalors don't seem to give me relief. i also have anxiet really bad alot of times and it may make it worse. I've been sleeping so much lately. :'( Please help. ty
