Proving that lines are parallel

Hi, I need help solving this problem - any help would be appreciated :)

\(P\) and \(Q\) are points on the bisector of the exterior angle \(A\) of triangle \(ABC\) with A between \(P\) and \(Q\), and \(PB\) is parallel to \(QC\). Point \(D\) is on BC such that \(DP=DQ\). Prove that \(AB\) is parallel to \(DQ\).
