I been constipated for 2 days. Could I have a bowel obstruction?

Last Friday nite, I ate a burrito and had diarrhea for about fours days. Yesterday my stomach finally calmed down but I didn't go at all, and I didn't have a bowel movement today either. I don't have any abdominal pain, but I feel more tired than normal. I been trying 2 eat better and been drinking water. However, I have been stressed out a lot, overworked having a job and running my own business at the same time (depending on how hectic things get, I can work up to 12 hours a day). And if im so busy i sometimes forget to eat. Lately I been stressed and my anxiety disorder is working over time. Does this stomach issues have to do with stress or is it a bowel obstruction?
