I have very mild autism, but that still affects my people skills. I feel like I cause my parents a lot of grief and stress because of it. My parents are atheists, see. I feel like I was sent by God as a punishment to them for rejecting him. I feel so terrible!
Be of good faith and trust God. How do you know that you weren't sent as a witness of Christ and that your parents may eventually come to a saving knowledge of the Lord through you! Praise God!
