If you are having trust issues, you may want to seek out professional help. If you tell friends and family, there's no telling who they may disclose your personal information with... other friends, co-workers, etc. Though it may cost a bit, you may want to consult a therapist. Therapists are sworn to secrecy, however, if you are committing violent acts against yourself or people around you, they do have legal obligation to inform your legal guardian(s) or the authorities. Do what you think is best with this advice in mind. Best of luck to you! You can also inbox me for more information at any time.
