Feeling Guilty After an Incident During Umrah

Assalamu alaikum everyone, I recently returned from performing Umrah with my mother during Ramadan. Alhamdulillah, it was a blessed journey, but something happened that's been weighing on my heart. While we were doing tawaf, the crowds were really intense-lots of pushing and shoving from all sides. I was trying to stay close to my mom since she didn't have her phone, and honestly, the combination of fasting in the heat and the crowded conditions left me feeling lightheaded and frustrated. As we were finishing tawaf, an elderly sister brushed forcefully past me. In that moment of frustration, I pushed back slightly. She didn't fall or get hurt, but she did say something in her language that sounded like a complaint. Now I can't stop thinking about it. She was fasting, probably in her 50s or 60s, dressed in layers in that heat, and I should have been more patient. The fact that this happened in the Haram makes me feel even worse. My question is: does this affect the validity of my Umrah? And since I can't find her to ask forgiveness directly, what should I do? Any advice would be appreciated. Jazakallah khair.
