William,
I'm very happy to hear that you're going to be teaching someone some of your many skills. I'm also very proud of you for keeping going in the face of such sadness. Life sure is "bittersweet"; so much happiness and laughter, so much pain and sadness. Please feel free to "lean on us" whenever you feel like it; you'll get through this, I feel very sure of that. Not "over it", as "gotrocks" (Norris) said, but through it.
I was wondering if you have any children or grandchildren close by? Family sure can help at times like these, but as I said, I think you've got a pretty big "family" right here, too.
Take care of yourself, do good things for yourself, and keep looking at all the good things that are still here for you to enjoy, including all the great memories you must have. In a very important way, no one is ever completely gone, once they've touched our lives.
You're in the thoughts of a lot of people ... hang in there, you'll make it.
John
