Hi AJ89! Welcome to Wrong Planet! Check out the many interesting and helpful forums here. It is not necessary to have every trait of any condition or disease in order to have the condition or disease. Go to the General Autism forum here at WP. There is at least one post there with links to online tests you can take to see if it is likely that you have an Autism spectrum disorder. Save the results of your online tests, and print out at least two copies. Keep one for your records. If you want an official diagnosis, bring the other copy with you to give to the psych doc. Only seek an official diagnosis from a psych doc who has experience working with people on the Autism spectrum. If you are an adult it would be best if the psych doc has experience with adults on the spectrum.
Hope this helps. You are among friends here at WP!
