Both options are suitable. It can be understood that sadness works as a vocative, in which case it is appropriate to write a comma, or as the term of the conjunction bye, with a meaning close to that of ‘sadness is over’, which justifies not using the comma. Similarly, one could write Hwave, happiness u Hello happiness (‘happiness arrives or begins’). It could also have been expressed as Agod to sadnesscase in which comma is not used either.
