Nothing has changed

Wow !!! I just looked back over my old journal entries and I realized nothing in my life has changed. I am still depressed and sad all the time. I really need to make some changes but I am not sure how to begin. How do you react when a family member has a massive heart attack    and needs help with aftercare, Dr. appointments, housing, etc.  and not one person steps up to do the right thing??? It makes me feel so sad and angry and ashamed. This is my family and it means I have failed miserably. How do i fix this? How do I make them see they are wrong? This is awful and it has affected my mental and physical health. My son has lost 2 thirds of his heart muscle from his heart attack, he will probably die soon and I can't even take care of him because of the people I live with. I don't know what to do. I feel so helpless. I feel like everyone has abandoned me including God.
