Okay it’s not great news but! I finally understand my panic attacks. Sometimes they would come out of nowhere with no trigger in sight, and the first symptoms were always increased heart rate/palpitations and being physically unable to breathe. I have been diagnosed with GAD already but Lexapro + Buspar wasn’t helping much with the attacks just with acute daily anxiety and worry. I went to a new doctor and he checked my lungs and did x-rays and I have FUCKING ASTHMA I can’t believe I was never diagnosed before this. He said the asthma and panic attacks seem closely linked and that stress must be a trigger for me. I have an inhaler now and I haven’t struggled to breathe during a panic attack since. It didn’t solve everything, but it did help! Posting this in case someone else has had the same struggle— get checked for asthma!
