I don't want to go too much into detail...but it's been brought to my attention that my parents are verbally abusive. They pin my siblings against me and encourage them to insult me and talk down on me, they yell often, blame all of their problems and fights on me, often yell, scream, and swear at me, compare me to my "more successful" younger sister, throw things at me, call me names, etc. They've been more recently pushing me to the point of a full on mental breakdown/anxiety attack where I sob uncontrollably, dig my nails into my own skin, rip out my hair, lose my ability to talk normally (stutter), hyperventilate, and lose all control over my emotions and actions- once I've reached that point, buckling under the criticism and yelling, they laugh. They laugh and they get mad at me for being dramatic.
I've seen it affect my little brother, who is currently in third grade. He sees me having these breakdowns and being yelled at, and he cries, but he gets too scared to speak up because he doesn't want to get yelled at too. I've seen him look at me in horror and look at my parents like they're going to scream at him too.
My sister likes to join in when this happens, and taunt me. And my parents verbally tell her that she is "justified".

I was told by a doctor that I have high anxiety, and I react the way that I do because of that...my parents often deny that I have anxiety, and my mother has even gone far enough to physically drag me out of a bathroom stall, crying and shaking- while having a panic attack- into a group class in a public space to humiliate me.

Recently, I've lost any impulse control and I've been spilling this information to my close friends...who immediately said they are going to "help" me by getting me removed from my household. The truth is, I feel like I'm overreacting. In the moment, I'm terrified and upset...but then things blow over and my parents are still my parents. I love them because they're my parents. I don't want things to fall apart and for it to be my fault. But my friends are worried about me...last time I mentioned anything to the counselor, I had been self-harming in a matter of speaking. I told my mother (against my will, after she'd gone through my phone and seen texts mentioning a visit to the school counselors), and both of my parents were upset that I was ruining their image and making them look bad.
I've been warned not to talk badly about my parents. Being taken away by the police has always been a looming fear. I don't want to be taken away from my family because my family is all I know. I am dependent on my parents and I can't imagine living without them. It makes me scared.

I need to know how to reassure my friends that I'm really fine...and that I can make it through these next two years of high school...I'm just terrified that after all the guilt and blaming that something might actually be my fault...I don't want my family to fall apart because of me. I already get told that my parents will divorce because of me...

When my dad goes off on me and my mom, my mom threatens to take me away from him. Just me, not my siblings...

I'm scared that that will become a reality...I don't want to ruin my family life. How do I convince my friends that I'll be okay, and what should I do...
