I feel you bro. When Penguin hit marketers I went $4.23 in red. After few months I recovered though, for today I'm around $3 on plus. I'm fully aware after I pay domain renewal fee I will be in red again. I predict a loss of around $5 this year. Life is hard, we need to hassle bro. Don't give up, I've just read a story of a guy (on Digital Point) who pulls $3 - $5 a day with AdSense. I've already PMed him from my DP account, I told him I need to know his secrets. I also negotiate a discount for a great new ebook with a guy from WaFo. He said I can pay installments which is very kind of him.
So you see, I don't give up. All the best my friend, the world is yours!
I also changed the bar below you so everyone knows you're in red.
