Kathy, i know that this is not the same as losing a son but I did lose my Dad so i just wanted to contribute if you don't mind.

I feel like My Dad is not there..he is around me..i light candles every night to "bring the angels" ( a friend of mine took an angel course and she learned this...cheezy..yes but comforing to me. i feel like he is always with me "in my heart". i still visit there but not too often. Take Care of yourself. Pand.
