Memoirs of the water in a river

I am a water in a water am I inconsequential but the water around me is
I have flown a way through all that is the streams that flow towards the ocean a vast mass of nothingness
Its sad to be water for I flow in one direction I can never experience anything twice though I have experienced most
Not sure wether the next stream or river will be nicer than the other
I am sure only that this stream now compares to the one in the past
I have regrets I can't undo rocks and pebbles I hit on my way through the little child I drowned the murder i drowned the good and the bad the regrets and the joy I can only experience once and never can I go back twice
