AITA for being the only one who cared.

I, 31 F, have always lived and taken care of my father who's in his 70s with many heath issues. I have 6 sisters and 2 brothers, a blended family. My mother died when I was 15 and the past 17 years, mainly the past 10 I've help my dad with everything. The last day of December my dad suddenly passed away. When we planned his funeral it came out that I, his caretaker and youngest child would receive his entire life insurance policy. Let me mention all of my siblings are 20 almost 30 years older than I am. They have grown children with homes and things they've had for years. Last year in April we sold my childhood home. My dad put $100,000 on our new home. My sisters are upset that our father basically "gave" me 100,000 for a house and left me his policy. But the thing is, when it came to taking care of him, getting him to point A to point B it was only me. No one ever offered to help with any of it. Of course when he was in the hospital everyone wanted to be there but most days it was just me, who worked a full time job and had two kids. I've been called spoiled, told I should rot in hell upon many other things. It's caused me deep sorrow and pain to know that my siblings are mad about something out of my control. AITA for feeling like they aren't entitled to any of it?
