Bitt,
I will, as the rest of us, pray for you and your wife during this time. Let me make several observations since I deal with this sort of thing a good bit...

1. Your belief in God does not affect His belief in you. I don't mean this in the cheesy "God doesn't believe in atheists" sense. Instead I mean that He will very much be with you in this time as it is in His nature to love those He has created.
2. The repetitive nature of your wife's hospitalization is by no means unique. Most individuals that require hospitalization will have to visit a facility more than once. Her needing this type of help does not shadow her recovery.
3. My wife suffers from low grade depression (if you know me in real life realize that this is less than public knowledge and keep you mouth shut.) I know exactly what you mean when you say any form of emotion is welcomed over the blank stare that seems to settle on a person.

If I can be of any help let me know. My prayers are with you.
