How or what can i say to get my doctor to prescribed xanax?

You go in for an evaluation, express your concerns and what you feel may help (if used in the past) and the doc will decide if it would be appropriate. As a schedule 4 controlled drug, the doc must have a special permit to prescribe it and must document the reasons for its use in a permanent record. Failure to do so can result in loss of the permit.

It sounds like you are interested in getting a specific drug, not in getting help for your condition or symptoms. Such an approach will make any doc cautious as this is not what is expected from a patient looking for help in general. Out of all benzodiazepines, alprazolam or Xanax is the most addictive.
