Match line breaks in lines that are not starting with a special character

Question

I want to match all \n or \r except the ones when the line starts with a @ I have this regular expression : (?!^@.*\r*\n*)(\r*\n*) For example:

@text text text 

@text text text
The line break after this text should be matched 
The line break after this text also should be selected 

@this line break should not be selected

So the only line breaks that should be selected are the ones in the 2nd, 4th, 5th,and 6th and 7th. Any ideas?

Note I do not SELECT the text, I REPLACE the \n\r or\n or \r

const text = document.getElementById("x").innerText;
document.getElementById("x").innerText=text.replace(/(^[^@].*)(\r\n|\r|\n)/gm,"$1<BR/>")

#x { font-family: "Courier New", monospace;
  white-space: pre; }

<div id="x">@line 1: text text text 
line 2:
@line3: text text text
line 4: The line break after this text should be matched 
line 5: The line break after this text also should be selected 
line 6:
@line 7: this line break should not be selected
</div>
