Need funds after a family tragedy

I had taken a loan on behalf of my brother to help him out in a start up business venture. Few months ago, he was hit by a car that jumped a red light and he had a severe head injury. Thank God, he is alive, but he has lost most of his memory and is currently not in a mental capacity to work or start his business that he had planned. He has no job and therefore no salary, and has no means to pay his loans, let alone pay for mine that I took on his behalf. Life has been a struggle since the accident as we are accumulating pennies to pay up liabilities. If you are blessed and able, please help us.
