You might be suffering from irritable bowel syndrome (IBS). This condition leads to bloating and diarrhea after meals. Foods that are fatty, contain dairy products or gluten may set it off. Try to stay away from these kinds of foods. When you are stressed out it can also make the situation worse so take it easy on yourself and do some light exercises like walking. Drinking lots of water will help with loose stool relief too.  I would recommend going to see a gastroenterologist who can provide further evaluation & treatment options.
