1997 Chrysler LHS many problems!

Whew, in the past 6 mos. I have had a regular tune-up, new brakes, new tires, o rings and fuel line, steering rack and pinion, u joints, whole wiper assembly, battery, oil pan gasket and oil changed, and other things replaced on my car, can't remember all the names. This week was told I need hubs and bearings, motor mounts, struts, head gaskets, and some bar that hold the whole front end together. The car still leaks oil, smells like gas each time I start it, is hard to start, leaking something pink, smells like something is burning when I turn the heater on, key often sticks in ignition, sometimes have a hard time getting the car out of reverse. What should I do? I'm an elderly lady, widow, on a small pension, handicap, and have no savings. This car is killing me!
