If you delete responses to your own question does that make you a drama queen?

Not necessarily. If the responses were deleted just because the poster disagreed with what was being said, even though it was said respectfully and was on topic, or they were deleted just out of pettiness, because they were upset with them for some reason, then yes, that's dramatic. But there are lots of valid reasons for deleting comments too, for example if they're disgusting or rude or off topic.
