&gt; it will probably help more than any amount of exercise ever will.<p>Unless the issue is solely anxiety-based, exercise would in most cases help a considerable amount. Especially for smaller medical concerns (not sleeping well, aches, mild anxiety), doctors usually cannot really help. Medical intervention generally does not make sense until something is really wrong, and a proper exercise habit is a very good way to help prevent many types of conditions. Before I had experience with doctors, I thought they would be able to solve any medical problems, but I learned the hard way that with many problems they often cannot help a significant amount, if at all. Medicine is still a very crude science. Plus, it would be a folly to think a doctor cares as much about your health as you do. If you care about yourself, you need to do your part with diet and exercise.
