I agree with Zoe.

And, uhm... There's one thing I just have to comment:

"the unexplained and extreme anxiety about the fact that the light in his brother's room is on a dimmer switch"

I always thought everyone was aware of that horrible sound dimmer switches make when they're turned on, and not set on max. To me, it's totally understandable to panic on that noise. But the solution I've made for myself is to simply avoid using the dimmer function (either off or on max). I'm sure that is a lot easier than to invent a pill taking away my personality and altering my brain structure.
