Cry if you want, why not, it releases and gets rid of toxins. Allow yourself a set period to grieve and feel angry.
Then stop.
Go do something else, occupy your emotions with something active. Play some wonderful music, dance, sing a long. Bake a cake or read. Try sudoku, anything to let go. paint a room, clean a drawer, draw a cartoon of H. Then go exercise.
Go GAL even if you don't want to.
The body and mind can only hold one emotion at a time. If you are actively doing another activity then the rest goes. That is my tactic.
Freedom is just another word for nothing left to loose. V 64, WAW
