I can understand why this could make you feel anxious. Something to maybe remember is that since the CPS case was closed, that means no one they talked to probably said anything too bad about you. And I don't think they could go around telling just anyone about your mental health history, probably it's them more collecting info from the people they interviewed than the other way around. Also, being a school it's possible they have dealt with this with other parents, not just you. Is this something you might want to discuss in therapy?
