I'd say it's been there for a while but it's taken a long time to just accept this. Its kind of like a schrodinger's cat thing and hoping it got better. It's weird and difficult to accept that your company that you pour everything into is built on fraud.
Well, don't think about it like that -- not every part of it was a fraud. There were a lot of good people working there, including yourself, with the best of intentions. I even think the people at the top had good intentions until they were led astray by greed or fear or whatever it is that make good people do bad things. Anyway, you're gonna come out of this a little bit wisher and better able to avoid these sorts of situations like this in the future. Also, you've got a good to years of experience -- that's going to look great no matter what.
