You can't lie about those specific hours required for graduation and licensing because the state won't grant you a license. Experience listed on a resume is much broader and would include any work you've done related to your career, including your internship and other jobs held before your degree was completed.

The reality is that most consumers of therapy do not go long term. Most people, in general, see Ts for a year or less and there are many reasons. Sometimes it's insurance but it's often not. Some people never find a T they click with, some people resolved the issues they sought help for, and some people just don't have the time and interest to make the effort to go. So a lack of long term clients isn't a negative mark on a Ts resume. That's just not where most of the work is in the mental health system.
