Hi Phoenix,
I can totally understand your fear of having a panic attack. I have that fear myself almost daily.
Are you taking meds? If so make sure you dont forget to take them right before you leave for the airport. Also, you might try taking some magazines or something with you that may keep your mind occupied during your trip. Try to think of it as a positive experience, after all... you are going HOME! Theres no place like home, right? lol.
Good luck to you. I'm sure you will be OK. :)
