I hope everything is fine. It's good thinking to call the Police. One time I was right on the edge of having too, because I was going to get attacked by my brother. But everything calmed down and became normal again. So I know how it feels to have to deal with that (sortof) but it must be worse for you, and my life isn't the subject of this thread anyway
I just hope your dad gets better soon, and that your problems are over.
