nervous system

You know how to handle hard things. But somewhere along the way, the part of you that learned to stay ready stopped being something you switch on when you need it and became the default. You are alert when you do not need to be. You cannot fully rest. You have been told to relax and genuinely cannot get there. This is not a character flaw. It is a nervous system that learned to do its job extremely well - and has not yet received the signal that the conditions have changed.
