(1) Get a lawyer.
(2) Pre-emptively see a psychiatrist or psychologist of your choosing so they can hear your story from you first, rather than from some panicking family member.
(3) Get a different job, one that does not involve children.
(4) AFTER convincing your family and the authorities that you do not pose a danger to children, and after the "order of apprehension" no longer is in effect, THEN move far, far away from your family and start a new life, and be more circumspect there. Being a fugitive doesn't sound like that great an option to me.
