I had a similar case in May 2012 with GMCR. The stock lost over 50% in the earnings night and my loss was huge. Today I am back on track. I recovered with other stocks mainly solar stocks, but if I would have kept also the GMCR stock which dropped from 50 to below 20, today it is over 75.
This is me too except thankfully I was in options instead of margin so I simply lost everything --- but not more than everything. I don't know what to tell you though man, that is rough. You'll have to declare bankruptcy. Eventually we'll both be ok though. Let's learn this lesson together, only play with what you can afford to lose, don't put all your eggs in one basket, and go easy on the leverage.
