I hate my life

My mom is a fucking asshat. We lost my mom's mom during Covid, and even though she did not die of Covid my mom has been an asshole about it ever since. And now my boyfriend who is like a son to her has gotten sick. He has to be tested but she is convinced he has it. He is not getting better and has to be tested again. She is furious he did not get tested earlier and is blaming me. I was the one who took him to the fucking emergency room. I tried to convince to get tested earlier but he would not listen. So she is blaming me. This is what being the only child does to your parents. We had to cancel his mom's birthday party because of this and she is also blaming me for ruining the birthday. I feel like the world is against. I just want to be gone.<br><br>EDIT I am not blaming my boyfriend for anything.
