This helped my husband understand my daily battles. 
I have 2 side of my brain. Left side is the anxiety, and it has a Mountain Dew chugging demon whispering all this shit in my ear. He’s cracked out and talking a mile a minute at volume 10. He rarely sleeps and a lot of things crack open a fresh Mountain Dew for him so he gets a burst of energy and goes hard for hours or days. 
The right side of my brain is my logical side. It battles to calm me down and says things like ok what are the odds of you actually having this disease/situation? But this side is tired because it’s a constant battle for peace and talks at level 2-like a whisper. It runs low on fuel and has to sleep sometimes. 
Of course it’s when the right thinks ok the brain is at peace let’s rest and enjoy my
Left side starts cracking opening mountain dews like it’s at a frat party and funneling them. I try to calm myself using logic but sometimes logic is exhausted from pulling 2-3 weeks straight. 
So there goes my left side screaming things I should worry about and this is where the panic attack comes from.
