We consider a linear elliptic problem with Dirichlet boundary conditions, with a potential term $b(x)u$ where the potential function $b$ behaves as $\frac{1}{\mathrm{dist}^2 (x, \partial \Omega)}$ close to the boundary. We study the effect of this potential term on the $H^2$ regularity of the solution of the problem. An application to a stationary Fokker-Planck-Smoluchowski equation for FENE models of diluted polymers is given.
