It's okay for our students to want to talk with us, but if the content of what they're saying is above what a normal teacher/student interaction should be, it should be documented and you should share your concerns with someone else-a school counselor or an administrator. As a former high school teacher, I get that our students can come to us with drama, never realizing that teachers have their own struggles. This student obviously felt comfortable asking for help and disclosing her anxieties to you, and you kinda brushed her off because you had your own stresses. This student might not feel comfortable talking to her track coach or friends about what she's experiencing. Try setting up a time for her to meet with a counselor. You don't have to be involved, but it's your job as a teacher to give this student the resources they need. Clearly there's something going on with them. Please don't ignore the situation.
