It's really up to you. I chose to seek a diagnosis after my sons were diagnosed ASD because I could tell that my previous diagnoses were inaccurate and Asperger's syndrome fit everything I was experiencing. It's generally a long and expensive process, fortunately this wasn't the case with me, but be ready for it. You also run the risk of being misdiagnosed (or perhaps properly diagnosed) something else. Depending on the diagnosis it could effect legal situations and employment opportunities. Just something to keep in mind. If you do go for a diagnosis I wish you all the best! It was the best decision I ever made, the weight of the world was lifted from my shoulders when I got the diagnosis, and I felt free to be my quirky Autistic self vs pretending to be "normal" all the time.
