Never be sorry to share words like this when somebody has passed. Their memories live on and in that way our loved ones live within us that much longer. You seem severely moved by this news - I would recommend that you reach out to friends and family to talk about Vito and your thoughts. If it gets too much, try counseling. I for one am not afraid to say that I have had to seek help.
My PMs are open to you, and to anybody, if you need somebody to talk to. I don't check my account nearly as often as I used to, but I will put in the effort to over the next several days. Don't stay quiet, reach out.
It ain't about what you are capable of, it's about what you're willing to do.
