loan shark settlement for my family

3 months ago, I borrowed USD 500 at online loan shark to fulfill the lives of my family and my mother-in-law. now my debt has become USD 1500. I was desperate. every day I was confused to pay debts, I almost lost my only job. debt has not diminished, but my assets, power also emotion have run out. I still have to provide for the lives of my wife, child and mother-in-law, I'm afraid of losing my job. I cry today, i could not afford enough meal for my 2 year old son, our money only left a dollar to live until tomorrow.
