Yes, I understand that because you are not allowed to leave the house, it is difficult for you to follow my previous advice and confide in a trusted adult. But dear, you are in your late teens. Surely you can slip out when the rest of the family is away, and somehow find access to a telephone. Under separate cover, I am sending you the 800 number of an agency which should be able to help.
But C., please don’t let your loneliness lead you to unrealistic fantasies. Don’t put your trust in imaginary fairy godmothers.
