Boldly confront the debt situations that scare you and contact your creditors. Ask for help as needed. Banks and credit card companies know what’s going on - talk to them.
See if key suppliers are able to give you more flexible terms/discounts/revenue deferrals.
Ask for what you need - don't ask for more than you need. Be a good citizen.
If you have cash, negotiate discounts. Some suppliers will be willing to trade value for cash.
