I would stop the email where you say you can't give more right now. He already knows all the stuff you do and if not he will probably take it as you complaining rather than explaining.
Did you talk to the mortgage company? Any hope of getting to stay in your house? I know you are going crazy right now but things will become more routine soon. Take a deep breath and keep on going!
