I'm very sorry for your loss, Bob. There are stages of grief, which we all must go through when a loved one passes, and it's never easy. Things change, they always do, nothing remains the same and none of us can predict with any certainty what the future may bring, so please give yourself some time to recover, and follow some of the excellent advice that others here are offering. There's message boards for grief and depression, community counseling, doctors and therapists, crisis phone hotlines, perhaps there's a local clergy person that you can speak with. Help is available, please try to take advantage of it. Take care of yourself, and I hope you feel better soon.
