i keep getting told my blood work is fine, but one bad day… and i crash hard. i realize my limiting factor isn’t just walking distance (the mailbox trip failure). idk, lately i think the intense energy drain from having to talk through complex things at work - like figuring out insurance codes or dealing w/ pointless admin meetings - is almost as bad as actually moving. is there a way people track the ‘mental’ crash? like, what level of cognitive effort really triggers PEM for you guys?
