choice of words

pangs of separation is perhaps how birhada or birha best translates

but that hardly captures the inevitable futility of the heartache

so i personally prefer the word longing at the moment
for the dark sleepless nights and endless days of torment 

longing’s less ambiguous in its outcome, as against separation

and yet more open-ended, more distressingly indefinite in duration 

it has a certain ring to it, an air of damned fatality

that is heartrendingly beautiful

and exquisitely tragic
