I probably should have updated sooner but, for everyone who replied about me trying to find my wayward father - I found him. Long story short, he was a Marine infantryman in Vietnam and has had severe PTSD my whole life. When he woke up to everything on fire in California's Camp Fire at the end of last year, he came so close to burning alive that he had to shave his head because his hair was singed. That experience sent him into a deep spiral where he "lost the ability to keep track of time".
