I am new to this group. I have a 10 year old daughter with sensory processing disorder (SPD), ODD, and not sure what else at the moment. She is on the go making demands 24/7. My son and I are exhausted. Recently, she tried to stab her brother with a pencil and bit a large chunk out of my arm. After a great deal of thinking and crying I sent her to go stay with my cousin for a while. She only acts like this at home; never at school. I feel like such a failure. . . the worst mom ever.
