Help for medical bills

Over this past weekend, my son had some issues that landed him in the ER and me out of work to care for him. I’m not sure what kind of bills are coming my way—ambulance, emergency room, etc. Along with that, I am on a small leave from work that will only get me about 50% pay, which I’m so grateful for but I still have bills to pay along with the holidays being here. Any help would be soooo appreciated
