I'm sorry you are feeling anxious.

For your facility to turn into a truly bad one, it would have to lose all these things:

top management
doctors
nursing staff
government agency that regulates it
board of directors, if any.

Plus, your family would have to die out or turn its back on you.

That seems very far from likely, doesn't it?

As for that flatmate, I don't think she's very nice or very intelligent. Let me tell you a parable.

Suppose that one day England was having an unusually hot August day. You look outside, and people are wiping perspiration off their faces and shedding whatever clothing you can.

You decide to go outside, and your flatmate says "Take a coat. It might snow."

You say, "That's not going to happen."

She says, "How do you know?"

Now the reasons you know it won't snow are complex, and they have been building up as part of your worldview since you were a little child. You can't summon up all the reasons and pop out an answer to your foolish flatmate, and she winds up looking smarter than she is.

Same with your facility. It's not going to turn into a nightmare overnight. But even if it starts going into a gradual decline, you aren't helpless like the people in the expose. You can speak, type, and use the Internet. And you have your family behind you.

I think you should get some good books and lose yourself in them for awhile until the horror of that program dies away.
