Give it a day or two and try again but only if you really want to. Being triggered is an awful thing and it throws the best of us off, even if we know the other party didn't mean it sometimes we think irrationally and she might come around and recognize that she did. If she responds the same way it might be worth telling her briefly you care for her but her reaction to you not knowing her trigger without her telling you hurt you and leave it be. If in a week or a month she decides to apologize just know you don't owe her anything.

To me, it honestly sounds like she just lost someone who would have helped her through her journey of getting sober.
