HOW CAN I GET HELP WITH A DENIED CLAIM FROM SOCIAL SECURITY DISABILTY FOR MY CHILD WHO HAS ADHD, URINATES THE BED, LIES AND STEAL?

I'm not sure that those issues qualifies as being disabled.  The definition is pretty conclusive that the disability has to affect the person's ability to live their life.  For an adult it means you have to be unable to work at all.  It sounds like you need to get more help form your daughter's school for behavior modification, and Individualized Education Plan and disability services.
