I really don't think she was being malicious. It seems like she was trying to say she understands that hardships come along with raising special needs children. I feel like she was trying to be nice, but said it very wrong.
MTE. OP, she didn't say you should be ashamed of your ds, she was just saying that its a shame he has to face the world with the challenges that come with Aspergers. She could have been a little more sensitive to your feelings and worded it differently but I don't think she meant to hurt you.
