I would suggest that you try a treatment to your eyes first, then try to use foundation. Try a ice-pack on your face first thing in the morning to help swelling. Then, a paste of cucumber and almond oil messaged under your eyes and leave for 10 minutes. Since you dont have any concealer, try patting down foundation a shade lighter than your skin tone under your eyes blending with moisterizer. Pat it with some powder, and your good Hope it works.
