If I were you I would definitely make life easier for myself, all the more so if you're not getting much out of it financially.
I heartily agree with Horsa when (s)he recommends the use of a course book. (S)he mentions "English File". This is the very best set of course books I have ever come across in all my teaching career and of COURSE it will give your student right from day one the everyday language she needs. It's true I've only used the intermediate and upper intermediate level books but there's no reason why the beginner's level book shouldn't be just as good as the higher level ones if the authors are the same, which I think they are.
You'd probably need to buy the accompanying teacher's book and if possible the corresponding CD or cassettes (although at a pinch you could just read out the tapescipts).
If for some reason you don't want to use a course book, in your place I would definitely give up and invent some excuse. The whole thing is obviously causing you a lot of worry and you've only got one life.
