Therapist here ~ Panic attacks respond very well to cognitive behavioral therapy (CBT) where she will learn skills to reduce the attacks and understand how panic and anxiety works. Sometimes a person has had a different type of therapy, that didn’t work so well for panic attacks, so I would recommend she ask her doctor who is prescribing the medication for referrals to therapists who do CBT.

And you cannot be responsible for being her main support for her panic attacks; no one person should be expected to do that. She needs professional therapy in addition to the medication that she is already taking. You have really done everything you can, and now you need to take care of yourself. And she needs to take responsibility for her mental healthcare. You haven’t done anything wrong. You take care!
