No. You're overthinking. People received these messages in all sorts of cases. Try to meditate, or do something that relaxes you.
As much as you need to be prepared, careful and alert, stressing too much isn't worth it.
What helped me personally, is thinking that I'm just going to DMV 😃😃😃
I mentally prepared myself that I had a clean, straightforward case. That I will be granted citizenship. That this is a formality I have go through, like a visit to DMV to get a DL renewal.
You don't want to be too relaxed, but at the same time, this helped me to reduce anxiety.
