It's okay to speak to your wife as if she is alive. I do this with loved ones and friend's I've lost and have found it quite therapeutic. What did the two of you enjoy doing together? Is it something you can do now, with others? In a group? If so, do that to honor your wife. Physical exertion is great; busy hands, quiet mind kind of thing. Paint a wall, scrub grout, clean windows, etc., something that, after you're finished, you'll be able to admire and remind yourself how good it feels to accomplish something. Get some sunshine. Open the blinds and drapes if they are closed. Get outside. Corny, but time does heal. Good luck, I'm rooting for you.
