First, Take a deep breath.
It isn't the end of the world if you are fired from a job that you feel you are unqualified to perform.
Next, analyze your siltation. Even if all the local schools are in cahoots to not hire you, so what? China is vast and varied. There is always another school, another province. That is, if you want to pursue teaching in China right now.
If you think you can "get it together", by all means take another shot at it. There are countless ESL teaching resource sites on the Internet. Middlekingdomlife.com maintains a list of excellent EFL teacher resources. Try getting up to speed with self study if you are going to try and persist in teaching.
If you decide maybe you need longer to get up to speed, consider going somewhere and taking a resident TEFL or TESOL course of some sort to get you ready.
It could be you are doing okay and are just insecure and operating without peers or feedback. On the other hand, you may be one of those never meant to teach. Only you can discern what your case is.
