PLEASE GOD HELP!!! CRACKED HEAD!?!?!?!?!?!

I started the car up and holy ****, the motor is skipping, and white smoke pouring out of the tailpipes, I checked the oil, nothing in the oil, no coolant, no dirt, nothing. Also the new coolant I put in the radiator seems to have dissapeared rather rapidly, what else could this be, if my head is cracked I am 100% ****ED!
 
If the head is cracked then coolant will go into the block most likely. Then you would see the dreaded milkshake. Coolant is obviously going somewhere and should be noticeable. Smoke coming out of both tailpipes or just one?
