What would be the point of the diagnosis at your age. You are obviously very successful at school and you have made it this far in life. Most services for autism are geared towards young children and those adults who would not be even able to contemplate college. A diagnosis on a record would just hold you back. People have their own idea of autism which may not remotely describe you.

By all means check out therapy and learn/practice social skills if that is what you need, but the label/diagnosis is not as significant as it would be if you were in elementary school.

Are there other young adults at your school who you know of that has this diagnosis? I ask because you will only be in therapy 1 hour a week and the rest of the time during the week is you practicing what you have done in therapy. As you no doubt know it's going to be work for you and someone else who is s similar will have some understanding.
