Are you crazy? It doesn't sound like that and what played in your head is what does happen. We can all ignore and pretend but how can one be prepared? It sounds to me it's a clear warning that private informations shouldn't be shared everywhere (FB is the worst place to be) and it's good to have someone you can trust and reach out to if you are in heed.
You have that person and it ended well so I hope you slept well.
