You cannot afford the "luxury" of staying inside your head...Get out now, physically and go for a walk...PLEASE. If nothing else, count your steps as you walk until it becomes easier. Then distract yourself with all that is around you. Turn off all devices that are delivering the "Chicken Little" theory of the SKY IS FALLING...which is everything and everywhere right now.
I often tell myself when faced with catastrophic thinking...What's the worst thing that could happen? I guess a normal person (unlike me) would respond "death". I disagree. You see, IMO we are all technically "dying" from the point of birth. Life is what we make it. Make yourself get out of your head and on the move.
You're no longer alone. We're here.
