Yes, I have been in your situation and I am sorry to hear you are going through this.
Is your business a limited company meaning you will not be liable for debts and will not lose your home, or are you in a sole tradership or partnership and therefore liable? That makes a huge difference. We lost everything. Our home and car were repossessed. We also had a small child to worry about.
Take everything in small steps. Try to stay calm; you need to practice some self-care even if its the last thing you are thinking of as you are going to have to be strong. See your GP if needed, try meditation Youtube vids, go out in nature, make sure you are eating ok - whatever you know helps you to keep it together.
You are your children's world and so long as you seem ok to them they will feel reassured.
You need to involve others who can help you out in this situation. Friends and family, free debt helplines, your bank, people you owe money to. Some people are kind and will help or be sympathetic. Don't put your head in the sand, you need to confront this head on. I found my MP was amazing and helped to negotiate with people for us. Their team also helped us find housing. Citizens Advice were also good for information.
I'm 15 years on from this now. We built back up and own our own home outright now and have a successful business. Our adult child is doing great. It was hard getting here and we had to accept for a while that our lifestyle had changed but we learned to find happiness in small things.
A lot of people go through this, especially these days. You will be ok, just take a little step each day to sort it out.
