I am the sister of a 21 year old with Aspergers, who does not accept that they have the condition, and it can be so frustrating.
She has no empathy and it is like talking to a brick wall. While you can reason with her, the effects are almost always temporary and after a few hours or days it is as though you had said nothing. You can make a reasonable suggestion or comment to her, and its like she doesn't process what you have said and often twists your words. Her Aspergers means that she can not understand how other people feel or what their intentions for things are, she can yell or get worked up over small things that most would dismiss. The main issue is that she cannot be rational or see that her viewpoint is wrong.
I really need some advice on how to handle this kind of irrational behaviour. She has anger issues that mean that she can be difficult to control, and I just need advice about how we could improve her behaviour. Has anyone else experienced something like this? My parents have mostly given up on trying to improve her behaviour. Any help would be appreciated
