Costs associated with Zack's car accident

On May 5th my son Zack was in a serious car accident in his Miata. Sadly his girlfriend Alivia, who he loved very much, lost her life in the accident. Zack suffered serious injuries and spent a week in the hospital. In addition to skull fractures and a brain bleed, he needed surgery to repair a broken clavicle. Due to not having insurance, we have incurred many out-of-pocket costs. He continues to need follow-up appointments with ortho and neurology. Each time he goes, we have to pay for X-rays and a CT scan of his brain in addition to the fee for the office visit. I have also been covering Zack's bills while we wait for his short-term disability to start paying. I am a single mom, and this puts a financial strain on me. Zack also has 2 children, one of which lives with him full time. I would appreciate any help during this difficult time. All money received will go directly to medical bills and Zack's rent, utilities, daycare expenses, etc. Thank you for taking the time to read this. Please share if you are able.
