Put in my resignation last week! I am far past being sad about leaving... the company I am leaving is nowhere near what it used to be, and it's only going to get worse. Glad I got out before the recession hits and before more cuts are made.
I was there a looooooooooooooong time, too.
Good luck to all who are left. Your next job doesn't have to be perfect, but use it as a step to get out of this sinking ship.
