Am I doing something wrong by acting estranged to survive emotional abuse?

posting a follow up because I am worried I am doing something wrong. I am a victim of abuse. my verbally and emotionally abusive mother has told me to kill myself before, how to do it, and told me to transfer my money to her bank account before I do it. she has told me to go to hell, and to get out of her house. she yells at me everyday for no reason even when I am being kind or just having a normal conversation because she is threatened by everything that I say. she is very narcissistic, and tries to control me, what I wear, how I stand, my finances, how I talk in work meetings, etc. she emotionally abuses my dad to the point where he thinks it's normal and has started slowly turning into her aka emotionally abusing me too. I have never been physically abused luckily. I felt like I needed to survive until I move out in two weeks. her behavior has caused me to think about suicide multiple times, and I cannot be depressed or cry anymore or else I cannot pack my things and leave. I became stone cold and stopped acting human in the house (no smiling, no emotion, no looking at her directly, short responses), walking like I am literally a disturbed and estranged person so that she would not talk to me and find a reason to abuse me. because everytime I act trusting or even look nice to talk to, she verbally and emotionally abuses me. I stopped eating with my parents and if I do, I stare straight blankly like I am crazy so that they wouldn't even strike a conversation with me and disrespect me. I stopped wearing nice clothing (only baggy sweaters with hoods to cover my face and sweatpants) and stopped playing music out loud or videos on my phone out loud in fear that she will think I am being friendly and human-like and start verbally abusing me. of course, I am nothing like this. I am very sociable and friendly, but I feel the need to act different in the house to not be dealt unruly with. am I doing something wrong?
