You're going to fail. Self-driling (or self-threading) drywalls screws are not used to attach stuff to drywall but rather to attach drywall to studs. Especially not heavy cabinets filled with glasses, plates, bowls, cups, etc. What you need are drywall anchors that go through and behind the drywall and then spread apart as you screw in the screw in order to attach firmly to the drywall from both sides.
Using screws without anchors in a drywall may be able to hold a light-weight photo frame, a wall clock, etc. But nothing heavier than around 3-4 lbs, that's where I would draw the line.
