I hope you can take as much time off of work and responsiblities, and have people help you. It is good that you two were able to say goodbye. At my grandmother's funeral, I had the instinct to tell her at the casket that she could go now and that we could take care of ourselves. So if there is anything you feel like saying to him, go ahead. When your time comes, you might just see him in the light waiting for you.
