Very sorry for your loss sir. I know that it may sound trite at the moment , but , you must now find ways to carry on. Grieving is a healthy thing , and the loss you have suffered is one I can barely contemplate. However , at some point you must return to living your life as I am certain your wife would wish you to. Thus you do honour to her memory , of this I am certain. In this you can count on friends (both real-world present and online) for support. My most sincere condolences.
