It's a state of mind kind of affair, i'd imagine. But i'm not there; i cant feel the senses given off, so i am only going by your words. I mean, if you're looking for advice, keep the love on. Keep faith, and keep telling him you love him. I know it's really tough to watch, it's tough first person, too. This illness doesn't just effect the sufferer, but those around them, too.

Empathy is a pure cure for psych numbing. I mean, there are medical ways to stabilize moods of course.

But, keep faith, and keep loving him no matter what. I know this is tough.
