Was a wrong for saying this to my mom

So long story story I grew up with my mom always working my dad was disabled and he slept all the time out of his control my dads passed away now but my parents used to SCREAM fight almost everyday I saw my dad try to cut his wrist with Kitchen knives and we lived with my oldest sister also that had 2 kids living with us as well that always worked and she would usually pick up me and my other older sister up from school and such while my mom was not home they used to scream fight all night keep us awake and we’ll it traumatized me and I have a lot of issues and fears today because of it I said something the other day about having traumas from my childhood and my mom got really mad saying she worked so hard and I never was saying she didn’t work hard to provide for us that doesn’t mean it wasn’t traumatic for me and now she won’t talk to me she literally stormed out of the room and slammed her bedroom door at I wrong in this situation? I’m 21 and trying my best to save for a house of my own but I’m not there just yet but I don’t feel comfortable being in my house anymore with my mom and stepdad…am I wrong for feeling this way and what can I do about this situation? I feel like for me to heal I need to move out get on my own and cut off my family but I know that’s extreme..they are just extremely toxic and in order for me to be the person I want and need to be for myself I can’t hold on to toxic people like that…opinions?
