Doctor or non-doctor, it's just a nam they call you. the important thing is what you do, what you think about and which position you are in their thought.
For the Vietnamese, in the first time, they just call us as a person who did the massage. But day after day, they will respect you and know clearly who we are. What do you think about when you go out and your patient see you and say that: he(she) is a physiotherapist who help me recover? Do you proud of that?
So, there are no reason why you changed your name about this.
