Sounds like a clear case of PTSD (Post Traumatic Stress Disorder) and understandably so. Tragedies like so suddenly losing a child or other close loved one (including pets in many cases) really have a way of rockin' a man's whole world... and it can stick to a man for many many years in some cases. Glad to hear you found something (God, family and fishing) (together) that made your hold your head up again.
