Well... having been in a vaguely similar situation about 2 years ago, I recommend picking your golden handcuffs and getting the fuck out before you stop caring all together.

Find a smaller company, identify what you find full filling in a team and work, and search for that. Salary second.

This is a whole lot easier to reason through while you can control it.

I also second others' mention of the importance of learning.

Or, sell your sanity. How much is it worth?
