I'm not a doctor, but I can act as if I were on Usenet...

Sounds like half of your brain is distracted by outside events and the other
half realizes that you aren't completely in control (or as safe while flying
as you should be) as a result. Hence the anxiety.
Time, and confronting your distracting issues is my Rx.
Good luck and fly safe.
