Brysing is right. You may have been cursed, but that is only a curse when you let it be. You think it to be a curse, than it is. You think positive and it's not a curse. It's what you think it is. It is a curse because you willed it to be.
if your still worried about it light a vanilla candle, its my cure all. get one at the dollar store and but it in the room in your house that gets the most traffic and let it burn all the way down. it cleanses all negative energy in your house and smells awesome to help calm you
