I'm so sorry this is happening. I know it is so hard to hear that from your child. This will sound lame, but please don't take what your son says personally. He is lashing out because he is angry and frustrated and wants you to fix it.. but you can't and so he is frustrated.

That doesn't mean you have to accept that behavior from him - you just cannot take it personally. You must challenge his behavior and help him choose more acceptable outlets for his frustration. Every special needs kid is unique - as you already know. Working with a specialist who is familiar with aspergers can help you work more effectively with him.

Don't despair - you are simply tired and burned out at this moment, which doesn't make you a bad parent. You are a great parent !! Please get hooked up with a professional who has experience with aspbergers - this is tough to go this alone, as you know.

Best of luck.
