Valmiki Ramayana Ayodhya Kanda Sarga 64 Shloka 75

आत्मभवः selfcreated on account of my son, अयम् this, शोकः sorrow, अनाथम् helpless, अचेतनम् insensible, माम् me, नदीरयः current of the river, कूलं यथा like the bank, वेगेन rapidly, संसादयति eroding.

This selfcreated grief is rapidly destroying me like the bank of a river eroded by its swift current, leaving me helpless and insensible.
