STICKY WASD/lag/control toggle/????

I go to the place where i build and i'll strafe to get to the angle i want.....but i keep strafing, i have to tap the button at least twice for it to become " unstuck". But there's nothing stuck! It happens to any of the 3 modes i play in. Its a glitch with THIS game, sticky buttons don't happen with ANY OF MY OTHER GAMES. Please help and respond quickly, i want to get it fixed or i want my money back, and i'll never play it again just because of how negatively this problem has impacted me.
