    some punctuation would go a long way; also some research - which do you think is correct & why. – gone fishin' again. May 29 '15 at 7:08
  • Welcome. Yes, it would really help someone answer your question if it was formatted correctly. Have a look at the edit to see what the changes look like. Secondly, and very importantly, we like to help people learn, so make sure you tell us exactly what doubts you have, or what you think the difference between the two sentences might be. We like to help, but we are not a correction service! – JMB May 29 '15 at 8:50

If I understand your question correctly, this is what you want to know.

Why are you worried?

...why you are worried.

The difference is simple. The first sentence is a question. That is also the reason why it contains inversion.

The second one is not a question, but a subclause which is the reason why it is not inverted. It does not form a complete sentence though, since it is only a subclause. A complete sentence would be, for example:

That is why you are worried.
