I'm looking for tips and advice on dealing with travel anxiety. I have an upcoming trip and I'll be alone for the first time in 4 years. I used to solo travel no problem, but the pandemic really did a number on my anxiety. 

My problem isn't flying itself, I'm not afraid of airplanes, but that an airplane is the worst possible place to have a panic attack (which I've only had one bad one, but it was one of the worst things I ever experienced). And when I'm anxious it sometimes affects my stomach but while an airplane is taking off I'm obviously going to be confined to my seat. It's really only the takeoff that gets me, once the airplane is at cruising altitude I'm pretty much fine and landing is whatever. But it's similar for longer bus rides or basically anywhere where I'm not 100% in control. My last trip was with my fiance and I used him a lot to calm myself but he won't be coming with me this time. 

So, tips, resources, and advice for dealing with travel anxiety?
