That's a deep poem, sometimes in life we go through things that weren't planned and after some time we happen to find ourselves in the same place where they happened, and a cascade of memories begins to arise ....
Sometimes, when the memory of it wasn't pleasurable as it was something bad, we might feel bad, our heart might race and we might run out of breath ... and we somehow remember what it felt like to go through such an experience. We begin to remember, and maybe we might start to admit that it might be the first step to forgiveness.
Sometimes people do not deserve forgiveness, how can we forgive people for what they have done to us. But forgiveness isn't about forgiving the other person ... forgiveness is a gift you give yourself .. and you are worthy of such a gift.
It might not be a coincidence that you found yourself back there .... no leaf falls if the unconscious does not want .... as I think you are ready to let it go and look to the future in a brighter way as what this poem conveys is your strength .... you are stronger than you can imagine ... and even if it might not be easy, just give it the time it needs and all will turn out well. I believe in you, Jenni ;)
