my comfort box/ groundding box is perfect for these times.
inside I have things that I can touch, smell, see and here.
just being around comforting objects, remembering the story of how you got them, and smelling them (having them in your hand, listening to the calming music), what ever, it really takes you back to a happier time- it does for me anyway
the other thing I do is watch the lion king (no other movie, it has to be the lion king)
after a couple bars of circle of life, I'm feeling a lot better- for you it could be a diffrent movie/ song
but simba is just sooooo adorable!
