My advice to the original poster is gardening or yoga, two very calming things that might get your life back on track. Chasing a phantom who took your money is pointless, unless you want to get on a plane and start knocking on doors. But sending emails to banks and US government agencies will get you nowhere. It's just going to leave a knawing hole in your stomach and every email back gives you false hope that someone will take up your case and retrieve your money, they won't. Move on, learn a hard lesson, don't buy half price cars on Craigslist from another country, these scammers rely on guys like you.
Your money is gone, there is no car, there is no Donna, and the guy that scammed you is going to be very very hard to catch, and it won't be by TD Bank, or the FBI.
