You have (at best) blown a head gasket, or (at worst) cracked the block of the engine.
Cars today, being mostly aluminum, break in this manner rather easily.
Repairs will cost you many hundreds or a few thousands of dollars. The car cannot be used until the engine is repaired.
God bless your efforts.
