My WAW was diagnosed with depression after she left. If there had not been OM, I would have probably gone back when she wanted to reconcile. But I could not get past OM issue and damage done. My experience is that DBing works but it takes a long time with a WAW. My experience better with the support of her family though, something it sounds like you don't have right now.
My advice is to keep on trying; only YOU can decide when to give up and that will be when you are ready to. Keep DBing, GAL but don't go too dark as a depressed person will probably see that as confirmation that they are unworthy anyway.
In terms of dealing with depression, I found a few useful message boards but I can't find their details anymore. My sugestion is that you should talk to your friends and family as they should be good listeners.
