Family in need of help

Hi, Im starting this gofund me in hopes to help out my sister Sonya Cote. As some of you may know, my sister and her boyfriend Chris have been together going on 29 years.  They have 4 children together 23, 19, 15 , and 14. They've always been a team.. this past November he was diagnosed with covid. He was brought to urgent care and then transported to the hospital with a very low oxygen level. He's now been in the hospital almost 60days and every day is a challenge for him. As of right now his o² is dangerously low without the help of the machines. He needs 70 leiters of constant oxygen to be pumped into him at every second of the day. He just lost his mom due to covid, and she feels like hes giving up. She's scared. Shes been told that this is going to be a long hard road ahead of her.. As of right now she's the main provider for her household and its just physically impossible. He was in an accident that totaled out her car about a week prior to getting covid, so she's been renting a car to make ends meet. She works all day to pay for her rent, utilities, the car rental, phone bills on top of her having to pay for his car loan & car insurance.. as of right now she needs about $3,000 so I'm asking for 3500 in hopes that it will make her life a little easier.
