Unfortunately, no. ODing on benzos alone will do nothing but make you black out. And I don't recommend it: You might do something stupid when you black out and end up in an even worse situation than you're in right now. That is, you might crash your car and end up a vegetable, or you might get in a fight with someone and end up in jail, or a million other things.
Benzos only work in combination with other drugs. You can mix them with alcohol or, even better, opioids. ODing on a mix of benzos and opioids would be my personal best bet.
