Abit dejected after trying to discuss late diagnosis with parents

Tried to talk to my parents about my late autism diagnosis tonight, they refused to acknowledge it at all, barely acknowledged I was even talking about anything. At 41 I wish my parents didnt still have the capacity to make me feel so naff. Feels like your being rejected for being different to what I imagine they hoped for. 

Lucky my wife supportive but still hurts. 

Just venting to those who may read and understand.
