Can my driver side mirror be replaced?

What is your question?

The mirror has been knocked off quite a few times. Friends have tried to help by gluing it together, but I'm pretty sure that should not be done again. I'd like it replaced professionally if it's possible. Car runs pretty well for being almost 30. I don't drive all that much. Thanks for reading. janice sanz
