I understand exactly what you feel. I lost my Dad in April, he also passed away alone. I still imagine everything, but I am starting to realise that "what if " changes nothing to make the hurt better. I love my Dad and I know he watches over me and has forgiven me for all I should have done and did not when he was still here, now I have to forgive myself. I feel with you, stay strong and try focus on the good memories. Joanne
