My advice is to get professional help even if you have to tow the car to a shop. Hopefully they can remove the broken plug without having to pull the head. Removing broken plugs can be a very tricky job especially when you are dealing with aluminum.
This advice comes from a retired mechanic who has screwed a number of times. Unfortunately, we often have to learn by our mistakes. You were just trying to do the right thing by using a torque wrench.
Please post what it takes to get your car back on the road. All of us who screw up will learn from your unfortunate experience. Thanks.
