All of your symptoms could be explained by depression, or it could be something else. A T or pdoc would want a general physical to rule out anything else. Sometimes emergency clinics don't shoulder all the responsibility for illness diagnosis if they don't perceive it as an immediate emergency issue. They would prefer you go to a family practice doc for a physical. So that might be why they didn't give you help with your stomach aches--they ruled out appendicitis or an acute abdomen (indicating serious abdominal injury) and sent you on your way, expecting you to follow up with your family doc.

When I was married to my first husband, I had a lot of aches and pains in my joints. They went away when I divorced him, after putting him through law school and supporting him for another 12 years after that. I was not aware at the time that I was under stress, but I guess I was. Went through a lot of therapy, exercise, no meds, and a long depression till I came out quite healthy and happy.

You're ahead of me, I think--you are aware you are bothered by things. I think you'll find a way to get to that doctor's appointment and tell them what you are thinking and how you are feeling and make a joint plan of action to determine the cause and work on a solution for you so you will feel better, whatever it is! Write and let us know how you are doing.
