I like the photo alot. There's a quiet, poetic beauty to it that is also rather heartbreaking. I'd say that although the mood is rather sad, there's some sort of hope in it, because you have the birds flying from a darker place to a much brighter one.
I hope that you're feeling much better. Photography for me is rather therapeutic and I definitely feel a lot better if I managed to shoot something I really like. It's also quite interesting to note what compositions you come up with when you're not your usual self.
