I just paid $3,300 for a diagnosis. I used a flexible spending account, which meant that that was pre-tax money. I felt that it was worth it, because of the possibility of having certain protections available to me in the future if they're needed(for example, in employment, and possibly some day unemployment). It also provided closure to know instead of just suspect for the rest of my life. I am glad that I went through with the diagnosis. It also led to diagnosis of not just autism, but some other things, as well. Keep that possibility in mind that autism might not be the only thing they diagnose you with, and that might provide you knowledge or might help you in some way.
