I very nearly had a panic attack Sunday night in bed. I self diagnosed it, as I've never really had one before.
I have since severely limited my news intake, and I'm back to my normal strange self. As said before, this too shall pass.
Sounds like you need to keep some Arko in arms reach from the bed for a happy sniff when you need it. I have some Tabac for the very same symptoms you describe, and it works!
