If your shelf screw is only in the drywall, especially just partially in the drywall, its going to rip out your wall. Make sure you have at least a 1-1.5inch of fastener after your shelf bracket. Get a stud finder and attach the screw to the studs (where available) If you dont have any studs to use, get drywall anchors which will help distribute the force.
