Mum is ridiculing me (all day) and when I get angry or annoyed she's like "It's a joke! It's your fault you can't understand that"

There's a difference between mean/ridiculing and a joke. I may have autism but that doesn't mean I don't get jokes. Lots of people say I have a great sense of humour. And even if I didn't, it's not my fault I have autism.

I really feel like crying.
