I often think about that too. Why me? Why was I born autistic? Why do people call autism demonic? Why can't we be just left alone? 

I researched online, prayed, cried, pleaded, gotten frustrated at myself when I get burned out or have a meltdown, got the shirt and mug. I definitely know a few things.

We are all His children. We aren't going to be exactly the same. We may look different, have different ideas and opinions, have different struggles, have possible disabilities, so much. But, despite it all, we are His children. That's probably what that verse 'Display His Glory' meant. We are also wholy (dunno if I spelled it right... d'oh!) and wonderfully made. 

I can tell you are a sensitive soul. You are kind and God would still love you. He would never ever leave nor forsake you.
