Hey there, I must say that my fiancé has Asperger's Syndrome, or ASD, and allows God to use her uniques to His advantage. Of course, being Aspie might have some areas that will affect your life, but it doesn't have to change your walk with God. For example, my fiancé, Sammy, has OCD, and while she was getting treatment, several people came to the LORD because she allowed God to use her at all times. Another way she works for the Lord is through directing a ministry through the university we attend that allows homeless people to get food and water. So, I would advise you to first seek the Lord in prayer and ask Him where you should step. Secondly, take time and study His Word. I know you have great memory, find some verses and tightly pack them in there. Third, you should find ministries that hit your interest and jump in! God loves the eager heart. So let God be joyful with your servants attitude.
I have Aspergers, so this reading is very helpful to me. I was beginning to despair, thinking I had no place in this world, and that no one cared about me, but now I have hope in knowing that at least God accepts me just as I am. He can use me in a ministry He knows is best for myself and others whom He places in my life.
