Your mother would have had no reason to understand, even if she was aware your father was vampire. No vampire that I have ever met, has power over fire. You are unique in that.
It is good, you're looking for help. Even just by talking about it, you're keeping it from building up so terribly again. I have said, I know little of controling the fire itself, but if you require help with the other... urges, that might hinder you while you work through this. That beast is something I know well.
