I know what you are going through!! Although I did my research and knew Yorkies were hyper, NOTHING could have prepared me for the craziness that was Rocco. He would run laps around my living room (sometimes over 100 times), climb on everything, steal things he shouldn't get, and still be super hyper even after walks. Visitors were always amazed and felt sorry for us.
Thankfully, he calmed down at about 18 months old. He is now pretty hyper in the mornings but lazy through the rest of the day. He will now let us put shirts on him and brush him. We can go out for walks without him trying to go 100 miles an hour. The difference is amazing! Hang in there. It gets much easier
