You might relate if you:

• Overthink decisions long after they're made.
• Replay conversations and worry that 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 good.
• Delay decisions out of fear of regretting them later.
• Feel responsible for everything and everyone.

This is often called high-functioning anxiety.

And it's more common than you think.
