I want to knock this kid out!!!!!

Having a child with Sensory Integration Disorder is such a burden!!!!!  There I said it.  Why me Why the f&*( me????????  I'm so sick of him doing ridiculous things in school and I get that "look" from the teacher.  I'm so f&*(ing sick of it.  I'm sick of going to get my daughter at her school and this child this thorn in my side constantly acts like there is something mentally wrong with him.  Not Sensory but like Retardation or something.  He spins around and crashes into the other mothers.  Today he rolled around on the ground in the rain mind you.  And proceeded to head but me.  I got ruff with him and push him away from me and yea it looks like I'm abusive.  I wanted to smack him I wanted to shake him.  I wanted him to play in Traffic!!!!!  Ahhhhhhh!  I am so angry right now that I literally told him do your homework or don't I don't care and I don't want you to speak to me at all.  Leave me alone and don't expect me to read you a book tonight.  I took away the TV and the computer which is like shooting myself in the foot right.  F^&* it!  I have to draw the line somewhere.  What makes me more mad than anything is that I complain about him and make us look bad.  He brings out the worst in me.  I'm soooooooooooo sick of it.  I just want to drive away sometimes and never come back. NEVER!
