I think it depends what kinda code you write. Also, what kinda management structure you find yourself in.

Sounds like you're writing code with hard specs (enterprise company?) where you just feel like a cog in this vast code outputting machine. In that case, it's totally natural to feel like you're dying inside. That's natural. We're creative beings, and you either need to find a different job or calibrate other dimensions of your life to meet that need (physical fitness, start a family, serious hobbies, be part of a community).
