I think you need to get down your local Citizens Advice Bureau today. Although if you did put your details into a phishing e-mail you will struggle to get the stolen money back, there are measures you can put in place to both keep the business running and keep your home until you can build up a cushion of cash again. You also need to ensure that you make a list of every single person you owe money to and take that along with you to the CAB.
Yes it's bad, but manage it right and you will get through it. Best of luck.
