hey man

i call that a case of the why mes .........where when u compare self to others never measure up (grass is greener on the other side of the fence type of thing)

so far i have not figure out any fool proof way of killing them when it starts but some stuff that alters it is
Kids or animals ........u go and play with them just distract self from the thinking and live in the now (can not be mad or sad with a laugh coming out) kids and animals are great for that

as for your wife going off she could of been blowing off steam about something else u are not aware of and with the way u are thinking it came off worst in your mind then it was ment to be

ummmmm.....u can try a mini vacation with your wife ( just a over night trip to something u guys enjoy ) kids stay with grandparents or a family u watch their kids when they need a break ............something like that will go a long way to destressing yah and getting head back in the game plus make the wife happy (happy wife happy life)..........the getaway would run yah about 400/500 bucks with a good hotel room for the night (nice bed and good bathroom) plus a dinner out and a show (just rem to bring home some nick nack for the kiddies and u are golden)
