What is the main conflict in Stuck in Neutral by Terry Trueman?

Fourteen-year-old Shawn McDaniel is convinced his father is trying to kill him, not out of anger but from love. Shawn has cerebral palsy (CP). A blood vessel in his brain burst when he was born, leaving him without any muscle control. This means Shawn cannot walk, lift his arms on his own accord, or even smile. Unfortunately, his family believes Shawn is not only completely physically inept, but they also assume his brain is dysfunctional. That is only partially true.
