A circle $C$ with radius 3 has diameter $\overline{AB}$. Within circle $C$, circle $D$ is internally tangent at point $A$. Circle $E$ is internally tangent to circle $C$, internally tangent to circle $D$, and tangent to $\overline{AB}$. The radius of circle $D$ is four times the radius of circle $E$. Express the radius of circle $D$ in the form $\sqrt{p}-q$, where $p$ and $q$ are positive integers, and find $p+q$.
