Take it to a local car shop and have it checked out. Apparently there is a problem if it is overheating, playing guessing games will not fix the problem. Best not take your chances.

if you want to test the thermostat just take it out and see if still overheats. you do not need a thermostat and when a thermostat goes bad it gets stuck closed so just removing it is the test for that.

other things that it could be is a bad water pump or a blown head gasket.

does the heater still work?

other than that it would have to be a bad hose or a leak

if you check your oil and see some milky like quality(or anything that does not look like oil) to it it is probably a blown head gasket and you should not run that car till fixed.
