It's not uncommon for a thermostat to stick as a result of engine overheating. I suggest not driving the vehicle until this issues is addressed. Overheating can cause extensive damage to your engine - if it hasn't already been done. I recommend replacing the thermostat and performing a block test on the engine. This test checks for hydrocarbons in the cooling system that would indicate engine damage from overheating. A professional technician, such as one from YourMechanic, can take care of this for you.
