My honda accord won't run. Help?!

So I broke down a week and a half 2 weeks ago on the side of the highway. As I broke down my thermostat was all the way as high as it could go, so i pulled over a bunch of grey whitish smoke came out from under my hood. i tried to start it again after it died and it wouldnt make a sound, the battery light came on and the oil light came on. (keep in mind my check engine light has been on 2 weeks prior to me breaking down, but got the codes read at auto zone and they said it was just my spark plugs) after sitting there for an hour, i try to start my car again and it starts, i turned around on the driveway and started going home because i don't have aaa and no one could help me out, as i'm driving my thermostat starts to shoot up again, and blowing out cold air. so i turned my hazards on and drove way under the speed limit on the highway doing about 40-45 so it wasn't working my car to hard. 5 mins from my house and i finally broke down and my car hasn't started since. I really messed up big time driving it but i didn't wanna leave it on the highway and had no way to get it back to my house! ),: Please help me figure out what's wrong if possible.
