What's the best way to ease the anxiety and panic attacks that i am experiencing concerning having another trigeminal neuralgia pain flare?

Keep The Faith: That's a 64 dollar question (OK, add 6 zeros to that). First, you need to be with a doctor you trust and who is available to you. Next, take the time to determine whatever medications will work for you (both on a chronic and acute basis) to whatever degree that might be--and treat yourself as soon as possible. Your doctor should help you with short-term use of an anti-anxiety medication.
