First of all do not drive it till you find the leak. You have probably damaged the head already letting it overheat. If you can't see any leak probably the head gasket.

 

Welcome to the forum, please post an intro in the new members area.

Follow police666's advice, but it doesn't sound good.

 

The plastic coolant reservoirs are prone to failure (cracking/leaking).
