<human>: Can you provide a brief overview of the text?

Hey Reddit, I can't sleep. I'm already having anxiety attacks, mini panic attacks.. I leave Saturday morning and I'm nervous about having a panic attack. I've been on 4 different plane rides in the past. This one is going to be 5h30m long. I've been on one which was 7 hours. But ever since I saw this video  I've been VERY nervous about having a panic attack. I just thought I'd give this a try, see if anyone had anything helpful to say. I'd appreciate anything at this point. If any of you had panic attacks in the past you'd know how much they suck and how hard it is to deal with them.
<bot>: I'm having panic attacks and I'm about to go real high up into the air where I have nowhere to escape to, how do I deal with it?
