The way you describe it, You mentioned MLC in context of yourself. Sounds like you were offering an understanding and empathy that it could happen to anyone given the right circumstances.
But you've put it out there, you mentioned it, she heard it. Leave it at that and let it alone. If she ever mentions it again, just listen. If she doesn't, it does not mean she didn't hear it.
Don't fret. It's in the past, it's over. Move on. Live now.
