Welcome to Wrong Planet!
Unless there is a tangible benefit to getting a diagnosis for adult Asperger's Syndrome, getting one can be costly, lengthy and sometimes detrimental to other parts of your life legally and professionally. But, it is, of course, your choice. Having a diagnosis helps some people despite the downside. For me, at least, I have learned to be satisfied with my University of Cambridge Autism Research Centre screening-test scores and my lifelong characteristics. They are the only "diagnosis" I need.
Either way, good luck!
