Copd diagnosis-some advice please

Hi, some advice please. I started to experience feelings of suffocation around 6 months ago. I have had mild ashma from the age of 40. I am now 64. I thought it was from my pet macaw who i have had for 20 years but recently moved into my living room. I had a spirometer and after around 8 tries as they could not get two readings the same. Apparently i had copd and didnt think too much about it, stupid me. A week ago i picked up a cold and could not breath, contstantly coughing , i was in a panic

Went to the doctors he told me my spirometer result months ago of 63 percent and had the lungs of an 83 year old. I thought if was a death sentence and have been in a panic ever since. He put me on steroid tablets and antibiotics, after 5 days and nothing improving he changed the antibiotics and doubled them up. Its been a week still mad coughing fits and feelings of cant breath cant shift mucus. Feel very weak a new experience for me. I have a reliever inhailor which i use. Feeling sorry for myself and trying to think posative. One of my big problems is anxiety which i have had for the past few years. I am trying to see some hope of getting back to normal. I am hoping someone can make me pull myself together. Thank you.
