I'd start here: "https://homeless.baltimorecity.gov/get-help-now". There's also Catholic Charities of Maryland (yeah, yeah, I know): "https://cc-md.org/". When I went to the BCPS, there was at least one student counselor per school. A few decades have gone by, and I am somewhat concerned that your post here would seemingly imply that the ratio of counselors has gotten worse over the years. If your site or region has a counselor, talk to that person.

CPS has a 24-hour line: "https://dhs.maryland.gov/child-protective-services/" There's a local office link on the left side of the web page that you can use for each jurisdiction in the state.
