Feelings Arising After Reviewing A Colleague

I gave feedback to a colleague in a performance review, and I’m struggling with my own feelings that arose from it. She cried, and expressed overwhelm and exhaustion. I felt that I conducted the meeting with compassion and support, but my feedback to her was that the presentation was not up to par. What I’m struggling with is that I made her cry and I made her feel freaked out and worried about her job security. All which are real issues. I could have glossed over her underwhelming presentation, because there are other parts of her performance that are strong. I’ve been doing models on this and still feel uncomfortable about how I contributed to her upset response. Can you help me navigate this,
