If I was in your position, I would have tried to get a raise instead of lingering in my mainly automated position -- ideally into another position I can automate. I don't want work to vanish from my head as soon as I leave my office, because that means it didn't particularly affect me in any way.
I don't think this is a particularly 'right' way to handle this. Some people want different things out of their work, and I think that's normal. You mentioned you're freelancing now -- are you doing stuff based off of what you were working on earlier, or did you switch paths?
