family issues

I'm having issues with who I am as a person rn and I have bad trust issues that make me not trust myself or others. I only have a Dad and a step mother in my life and it doesn't seem like they care about me. They put objects before me (i.e: I was in my first car accident on Tuesday night and they didn't care about my well being, didn't believe what happened, and cared more about the car) and then told the whole family during thanksgiving that I lied and made me look like a liar. I'm really feeling down about myself and I feel that no one cares. I just don't know anymore.
