I just came back home, then I was gonna take my phone until My cousin's mother lied about how I'm hurting her when I didn't

Then her husband said that I'm worthless and never existed and born, then he wished me to be dead in the car accident and then I went to my room and I overheard she said that she was joking around, until I got sad and I'm tearing up rn. everyone thinks that im such a happy cheerful person and that i have it all together but really im dying inside, i don't have it all together, im slowly falling apart. I hurt myself on the inside to kill the pain on the inside. Like what I am? An animal brat or what? what did I even do to deserve this man..
