It must be difficult for you.
First it is important to discuss with your GP as the cause and co morbid problems like depression and generalized anxiety
needs to be looked in to.Please note that I am not suggesting you have the, but informing the usually course of action.
Once the co morbid problems have been ruled out then there are two ways of managing this .
1. In the short term you can discuss the option of low dose of benzodiazepines like Diazepam 2 mg or Lorazepam 0.5 mg prior to your journey (Your doctor might be comfortable to consider of it is short term based and you are not traveling alone). If it is Lorazepam take about 45 min prior to the boarding. But, the prescription of these medication obviously depends on any other physical illness you have and also after your doctor feels they are safe to prescribe for you.
2. In the longterm, you might need help from psychological therapies like Cognitive behavioral therapy from practice counselor or primary care liaison team if there are no co morbid problems like depression.if there are then your GP might choose to refer you to local Community mental health team to address both. The medication like SSRI (either citalopram low dose or Sertraline Or other tablets depending on the medical history might be considered if needed).
3.Finally, for the trip a head, one practical thing that might help is --You buy a bottle of water after you check in and keep with you. Take small sips when you feel anxious and having dry mouth. The worse period is between you are in flight and it takes off as the crew would not supply water and it might increase the anxiety which might escalate panic attacks. Also, try to distract from the first thought f having panic attack and distract yourself by talking to someone or having small sips of water etc.once the flight takes off the problem would be less severe.
I hope you would feel better and able to enjoy your trip it India.
I wish you all the best.
