If things are getting that scary, maybe you should put the car in the garage and cover it up for a month or two. It wont hurt you to store it until you come to a final decision.
Selling the car sounds easy but you will stir up an entirely different set a emotions and problems when you actually do it. There's not a lot of people with the cash to buy someones dream.
Last time I checked, a mans dream is worth quite a bit of money.
I hope everything works out for you,
