The minor has no options. A friend or anyone else who knows about your issues or history can disclose them to anyone he or she likes. There is no law preventing person A from revealing health history, physical or mental conditions, suicide attempts, etc. of person B to others. The laws that restrict disclose of this information are very restrictive and would not apply to the minor's friends: a health care provider cannot disclose this, for example, and an employer who is told by an employee about disabilities and medical conditions is limited in whom it can disclose them to (basically, to certain persons with a legitimate "need to know"), but none of those laws restrict a current or former friend.
