Regret for speaking harshly to one's mother

Q: I am 21 years old. I love my mother but I spoke harshly to her today relating to my marriage issues and she cried. My father died when I was young and she alone raised me. I've hurt her today very badly. I've said sorry to her but I just can't get it out of my head that my mother cried because of me. Can you please tell me what should I pray to erase this mighty sin off my shoulders?
