it's almost impossible to explain it..
it is just when everything gets so overwhelming,you feel like you are spinning out of control,
every emotion is coming up on you in waves,
the only thing you can do to stop it all, it cut,the outter pain dilutes the torment inside..
you feel it physically & can handle that aspect of it better,
it's kinda like,popping a ballon filled with water,it releases the pressure....
make any sense?
