It isn't that you don't care about your family, it's just that you know they would never believe you. Nor would they take your word over a fancy priest from an even fancier holy order. There is also that whole matter of magic you'd have to let them in on, which is fairy-tale level stuff that would get you put into a sanitorium.
When it becomes evident that they won't do anything, you realize it's time for you to do something. Whatever that something is, you feel safer with a sword by your side. After picking up your blade, you whisper a prayer for safety and head out into the living room.
All right, Ronald Dunhall. You've gotten this far, but where do you go from here? The adrenaline pumps through your arms and legs, but you need to be thinking right now.

Nothing comes up. No scenario, nothing. There is one chance, if you're desperate enough for it. You could enter that 'complete focus' state you do for casting magic. Clarity and a certain wisdom are sure to come to you, allowing you to find a solution. But it isn't exactly a…safe state of mind to be in. Especially not for the house's resale value.
