i am sorry you are struggling... i am very much in the same spot as you... things that help me

run on my treadmill till i can't run anymore
take a hot shower (be careful with this one.., i found myself using it)
walk outside barefoot...
call my sons
type a prase over and over until you fill a word document... if you still want to reduce the font size and type someore... refocus on the kids in my class...
call my t ( i am not so good at that one)

please stay safe... i care...lyn
