To simplify the expression:
$-q - (-9q - q + 3) - 10q$

1. Start by simplifying the part inside the parentheses:
   $-9q - q + 3 = -10q + 3$

2. Substitute this back into the expression:
   $-q - (-10q + 3) - 10q$

3. Remove the parentheses by distributing the negative sign:
   $-q + 10q - 3 - 10q$

4. Now combine like terms:
   $-q + 10q - 10q = -q$

So the simplified expression is:
$-q - 3$
