I think if it were me, I would keep them safely stored away for a while. Take them out every year or so and look at them and see how you feel. Years from now you may be very glad to have them and able to look at them with smiles instead of tears. Time won't take away all the pain of losing your mom (I lost my dad in 1996- and it still hurts) but it will get better!! Sending prayers and good thoughts your way!
