Thats terrible.
Car's head gaskit is blown. You Will have to replace that. Try not to drive ur car at all and tow it to mechanic.
Two years back my JDM honda life had exact same problem. Stupid me, tried to fill in water again and again and drive it. Her engine was blown and had to replace engine assembly. I highly recommend u to tow it to mechanic. Do NOT drive it after just filling water or u may damage engine.
