I'm really sorry you experienced that. It would completely set me off too. I experienced the full pat down routine flying home from Turkey one year, because something on me set off the security sensors - it really freaked me out, so you''re not alone. I didn't completely lose it, because I was sort of able to semi-dissociate. (Dissociation has it's advantages). I just kept repeating over and over in my mind, this is not really me - she's just touching a body - it's not me. May sound weird, but it worked.

I don't know how far you are from your grandfather, but is there anyway you could take the train instead? It might take longer, but it might be worth it to avoid the security at the airport.

Good luck.
