There are lots of nonprofit counseling services out there that will charge them a sliding scale fee (or nothing) depending on their financial situation. Maybe their local Catholic Charities or other nonprofit organization (note: they don't have to be Catholic to get help from this organization. They are a federal 501(c)(3) organization, meaning they help everyone, regardless of their faith). They should also talk to the school counselor or principal. They probably know of resources that they might be eligible for. They should also realize that these may just be symptoms of a much bigger issue, such as a learning disability, depression, or drug use.
