You might relate if you:

• Overthink decisions long after they're made
• Replay conversations and worry you said the wrong thing
• Feel pressure to get everything right
• Struggle with perfectionism and fear of failure
• Feel mentally exhausted even when life looks successful
• Delay decisions because you're afraid of regret
• Feel responsible for everything and everyone

This is often called high-functioning anxiety.

And it's more common than you think.
