I understand stand your concern.
You doctor could prescribe your medication to calm your nerves and maybe help you sleep while you are in flight.
I am not sure if the airline would allow it or not but if you could carry a little battery operated fan to keep on you so you could feel air in your face.
I would contact the airline to see if they allow that.

Treating phobias, including claustrophobia, relies on psychological methods.
Depending on the person, some of these methods may include:
this is a form of exposure treatment, where the person is exposed to their phobic trigger until the anxiety attack passes. The realisation that they have encountered their most dreaded object or situation, and come to no actual harm, can be a powerful form of therapy.
if the person is far too fearful to attempt flooding, then counter-conditioning can be an option. The person is taught to use specific relaxation and visualisation techniques when experiencing phobia-related anxiety. The phobic trigger is slowly introduced, step-by-step, while the person concentrates on attaining physical and mental relaxation. Eventually, they can confront the source of their fear without feeling anxious. This is known as systematic desensitisation.
the person watches other people confront the phobic trigger without fear and is encouraged to imitate that confidence.
~Cognitive behaviour therapy (CBT)
- the person is encouraged to confront and change the specific thoughts and attitudes that lead to feelings of fear.
- such as tranquillisers and antidepressants. Drugs known as beta blockers may be used to treat the physical symptoms of anxiety, such as a pounding heart.
