Okay, that sucks. Might want to get in touch with as many companies as you can, explain the situation and see if you can work something out.
If you can communicate that you’ll need more time, I think they would prefer that over not getting any money at all.
When you are in deep shit like this, speak about it. Let everyone who you still own money know that you want to, but cannot pay right now and you want to work out an arrangement.
Also check if the government has a program to assist with debt. Be proactive, people are more willing to work with someone that is taking action to change things up.
The worst thing you can do is stop opening mail and just ignore it. It will only make the problems bigger. Get help, anywhere you can.
Good luck.
Edit: depending on your country and relationship with your employer, consider informing your employer too. Some employers are willing to work something out with you if you explain how it happened and how you want to get out of it.
