Incomplete evacuation of stool & weight loss?

yes it could be stressed, if your not pooping its probably because your not really eating... try eating and not to think so negative....the mind can do crazy things.... for the constipation... drink a gl of prune juice.. that should have you on the toilet....try those things....if nothing is helping... go to a different doctor for a second opinion? It sounds like your just stressed or depressed to me..
