Car Issues…blown Head Gasket and Antifreeze Leak?

I have a 1997 Ford Contour GL with almost 112kmi. Last week when I was driving the car at 55 mph the car started lurching forward…kind of like how it feels when you just tap on the accelerator and it jumps forward. I pulled over and turned the car off to check for leaks and a flat tire, nothing happened. Went to turn the car back on (worked) and started driving home…which was about half a mile. As soon as I started driving (20 mph) the front of the car started to shake really bad (is not the alignment), made groaning and whaling noises, and would not accelerate above 25 mph. When I finally made it home I turned off the engine, went to call my mechanic, and he told me to turn it back on but it wouldn't start. I have to wait two more days until I can get the car looked at but in the mean time I tried to jump start the car to see if it would start. It took about 3 tries and then just letting the car charge from my moms car and it finally worked. Now the car's exhaust is spewing white and the antifreeze is brown/rusted but not too low. It's also idling really rough and over heats within a minute. I have never missed an oil change, so that isn't the issue. I also have an over heating issue and my temp gauge isn't registering it (I think that's just broken). I just want to know if anyone else has had this issue or knows what it could be. I've been told it may be a blow gasket and an antifreeze leak into the oil. Wanted some opinions before it gets looked at in 2 days. I'm trying to figure out if it is too bad a fix and if I should just get a new car. Please do NOT answer this if you have no intention on giving me advise for what may be wrong with the car.

Suggestion:

yes sounds like the head gasket but also could be the intaake manifold gasket and my advise is to buy a new car
