My Lower Abdomen Hurts, Constipation And Diarrhea On And Off

my lower abdomen hurts, constipation and diarrhea on and off and a bit of nausea. I lost my mother and daughter within 5 days of each other 6 months ago and it seems to have gotten worse, I do not eat right, cry a lot and depressed could these issues cause these problems? I do have a bit of divuticulitis also
