Looking at what you already listen to I would suggest a few:
Slow Reader (this one can be hard to find but it's an absolutely incredible album. A must for any emo-indie fan)
The Promise Ring-Woodwater (I love listening to this in the fall)
Also check out Portishead
ummy and Morcheeba:Who can you trust? It's a different type of music (trip-hop) than what you mentioned but can be very enjoyable for what you are dealing with.
Me personally, I always retreat to Nine Inch Nails. But I'm a sadistic fuck and I like to exhaust my depression rather than ease out of it. Not that I disagree with your method, just explaining my own.
