I yammer with Katy Weber for over an hour on @womenandADHD. Not up for that? Here are the basics of beating brain fog and burnout.
limit processed bread and sugar
laugh or connect with a friend
limit noise "pollution"-seek out quiet
head outside into nature
wind down without electronics before you need to go to sleep and....
get 8 hours of Zzzzzzs
This isn't self care, it's self preservation. You will feel the fog lift, self-sabotaging thoughts fade and your confidence rise.
