Think of your nervous system like a cup that holds everything you’re managing such as stress, emotions, grief, responsibilities. When your cup has space, you're within your window of tolerance, meaning you can handle challenges with presence and flexibility. But when too much gets added and the cup overflows, you may feel anxious, overwhelmed, or shut down. The goal isn’t to keep the cup empty, but to recognize when it’s full and refill yourself with care, support, and regulation.
