Desperately need help financially

I want to introduce myself (Kim-52) I am a Respiratory Therapist and a mother of two. My daughter (Karina -18), and my son (Kristian- 14). My life story is one that has many avenues that have no end in site. My entire family has been in the hospital since birth, medical bills over and over. My husband left me when both children were in their early years of life with only a mother to try to raise them and deal with all the medical issues. Karina has had a one major heart surgery and is on a lifetime of medication for the heart, then she developed severe anxiety for all the hospital stays and worrying that her heart will fail. Kristian was hospitalized when he was young for Upper GI, Brain Tumor (removed 2022), Severe Allergies, RSV X2 that was severe. Kim now has developed an auto immune disorder (PBC), Developed Varices in her throat that I have had 6 procedures so far, and more to come. My liver is cirrhotic and I am in need of a transplant. I cannot imagine what tomorrow will bring because each day is something different, sometimes worse, sometimes the same. I can barely afford gas and groceries for my family. We are struggling and need help to pay for bills, a place to live, and car that is reliable to get back and forth to work, doctor appointments, and the hospital. The vehicle I currently own has had major work done on it; I am still trying to make payments, there is no air conditioning in this hot weather and I never know when it is going to break down again. I cannot imagine anyone going through what I have for the past 18 years, struggling and still struggling to this day. I cannot imagine me dying and my children not having a mother, a place to live, food on the table, a way for Karina to take care of Kristian until he finishes school. This is any parents worse nightmare. No one wants to ask for help for the embarrassment and shame. never have reached out to anyone before.My family has scrapped by some days only eating one meal at best just to put gas in the car and pay the utility bill. I cannot begin to tell the stories of struggle. I wish this upon no one and never thought in my early life I will go down this road. I love my children more than life, I am at the point I cannot continue to provide even the merger necessities of life for them. I am praying someone will read my family story and find it in their heart to reach out to me and my family and help provide some type of assistance. Again, this is not something I ever wanted to do, I thought I could do this on my own, I cannot. Please help!!
