Sounds like there may be two issues with regards to panic attacks and physical symptoms: 1) shortness of breath and 2) lump in the throat. The shortness of breath from panic attacks only last for a few minutes, while with asthma, it can last hours. And with lump in the throat, it is a common anxiety side effect: https://anxietyboss.com/does-anxiety-cause-lump-in-the-throat/
. Just continue to educate her that these physical symptoms are connected with anxiety, especially if they only last a few minutes. On the other hand, she will know when she has a full-blown asthma attack. So the work in therapy is helping her to understand the difference, and this psychoeducation can help her to distinguish between anxiety and asthma, then she can make logical choices from those attributions. It's like with my patients with seizures and panic...we spend a lot of time going over what is medical (loss of consciousness, urinating on self while convulsing), and what is psychological.
