I'm sorry you had this distressing experience.
Yes, I'm quite certain every one of us has, at one time or another, said or done things that were hurtful to someone else. I know in my own life I have been, at various times, both victim & perpetrator.
I'm a student of the ancient Tibetan Buddhist "Lojong" teachings. And one of the primary objectives of these teachings is to help us come to the realization that the joys & sorrows, hopes & fears we feel as individuals are the same joys & sorrows, hopes & fears that are felt by all people everywhere. "We're all in this together," as the Buddhist nun Pema Chödrön has written. I send hugs your way... with the hope that you will be able to find deep peace within...
