How is this even remotely an emergency?
There's no way to tell you how long your mid-2012 battery should last without a comprehensive study of how you use it. And even then that wouldn't take into account potential factors like defects.
For comparison purposes, here's the report from my mid-2012 MBP, courtesy CoconutBattery (which is free). Please note that this is not the original battery; it was replaced with a third-party battery before I bought it used, so it's fairly new:
Typically, a MacBook Pro battery will last many more cycles than what you've got listed for yours -- it should handily outlive the typical four-year replacement cycle for such machines, but under normal use will gently fade in capacity over that time. This is perfectly normal.
The latest MBP's have improved batteries (that are also sealed and not replaceable) that normally keep nearly-full capacity for quite a few years before gently fading. Hope that helps.
