Please Help

ok so the the other day my car started hard like something was hanging up then all of a sudden a loud scraping sound and it started up i noticed a loss of power steering and my voltage gauge slowly going down i got it home the belt was loose but no pulleys seem to be damaged or out of place it was sqeeling so i took the belt off and the squeeling went away im assuming the loose belt was slipping at higher rpms the noise would go away now i notice that it seems im getting antifreeze in my exaust white smoke and i can visibly see it leaking out of an exaust leak i have mid way under the car it it a head gasket or a cracked head or what someone please help me

Sounds like a water pump failure. If you can't visually see the smoke or antifreeze smell from the tail pipe it is most likely finding its way to your very hot exhaust system.
