It is probably the lower intake manifold gasket leaking and not the head gasket if your oil and/or coolant looks OK. There is an excellent video on here that is about a half hour that shows you how to do it step by step if you are interested. If you need a link to it, let me know. Otherwise, sad to see it go....I know how much this is eating away at you, but a reliable vehicle is important if it is your only one. Good luck with whatever you choose to do.
