Howdy Auntie: welcome to the board! If you get a chance there's a thread under open titled "getting to know you". Gives you some grins and giggles learning about us and - if you're so inclined - tell us something about you!
As for your question: go with what the Dr says, take it back to your LBS and make sure your handlebars are set right for you including width. As for the brakes, there should be an adjustment screw in the hoods that will allow you to move the levers closer to your hand. Your LBS should be able to make that adjustment for you also. They do make some WSD brake levers, you might ask your LBS about them, see if they carry them or can get them for you.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
