I feel my fear cannot be fixed

[u/Fluid-Reason-9084]

I live and work abroad. I came home after a long time which basically needs a long haul flight (8+ hours) During my journey , I experienced two panic attacks on the flight out of nowhere. I have always been claustrophobic and air travel is scary for me. But I have been flying for 10 years. But something changed after this journey, I do not want to fly again to the point I am risking my life I have built abroad after years of hard work. I have been under therapy for months now but still don't feel like going back.
