Replies to sharing that you are autistic.

I’m just venting to be honest, I’ve had a bit of a rollercoaster week, as many of you know, I was diagnosed this week. 
I’ve only told my mother and sister, both were fine and obviously a few questions.

My wife was phoning her sister tonight, so I said it was fine for my wife to share my diagnosis. I heard a very condescending voice say,” well how does that change anything?”

I now feel totally deflated and angry.

I wonder if anyone else has had negative replies? I do mean wether diagnosed or self identifying.
