Some technicalities may be creeping into the picture. If you receive "full scholarship for school", you probably do NOT provide over half your own support. Scholarships are considered third party support and are neither support provided by the student or by his parents. This makes a difference in the slightly different support rules for a Qualifying child and a qualifying relative.
If you are not living at home only because you are away at school (even if living off campus), you may still be considered as still living with your parents.
