NParent Trying To Take Over Everything, What Should I Do?

Look, i don't know what to do.

History: Covid period, she was harassing me like field days for online school in high school, I told counselors, got CPS called 3 times, same officers twice sided with her and called me a kid trying to do playtime, didn't eat or sleep for two days from the harassment, ran to the police station where a kind stranger preferred that i didn't get mugged dragging several bags at once, officer at police station told me to call her for asking to legally let her decide if i can go to a shelter, she minimized and giggled about it, i nervously laughed, officer purposely lied that it was a "sign of affection for her and that i loved her", then manipulated and pressured me to give up external family members (flying monkeys) details for them to pick me up (theyre on her side, of course i didnt want to say them), they kept me for a week, tried manipulation sessions and i appeared as if i was cooperative just to have them let me go because they were refusing to help after hearing "your sister is abusing me and it's illegal", i went back, nparent searched my phone, i told teachers home was "very noisy" for late schoolwork, cps was reported to, third time new officer, i was tired and quit even if they seemed nice, i decided to graduate high school, get a job and leave solo, skipped for a year off from college or so, did some classes, she was still annoying so i still have to finish my degree, i focused on work, new workplace was too far, ate all my grant money for uber, new workplace was toxic , quit, had no employment since then, was harassed daily by nparent whenever eating or showering so i avoided both and ate a lot of take out, cc maxed now, no job a year later

Now, nparent has been more aggressive recently, she threw several massive tantrums, scheduled on alarms at every half or so hour for a week straight, starting by screaming over me eating fruits she bought claiming "too many at once", then nstepdad came by the bext week, she started doing covert shit, stalking me in the bathroom at 4am when i tried to lie to keep her off of tracking me down for when i shower( always knocking on the door over dumb shit or screaming at you everytime you shower type harassment), then opening the door all happy that she forced me to encounter her, then kept doing digs at me, random confrontations more often, any chance she gets when nstepdad isn't around, "why didn't you shave your armpits, why didn't you shower, why is your hair matted, etc" unprovoked at different times, even if grey rocked and avoided, she keeps hyperfocusing on forcing me to take One A Day vitamins, while accusing me of being heavily underweight and skinny, when vitamins are never needed, (she tried to spike my food with it without consent a year before until i reported it to the police, the police still sided with her because it's not harmful he said), she tried to force me to switch to an iphone from android but iphone has a lot of exploits like location tracking that other people force on your phone, and no features to stop phone investigations, so i kept turning it down, she bought it anyway, and harasses me about it, she also uses a Ring Camera to pretend to watch doordashers arrive but she uses it to rewatch videos of me going to interviews, screaming hallucinations about how i walk stupid or look downwards all the time or look homeless, so she throws tantrums just from watching videos even if ive never physically seen her once in the past week, after nstepdad left, she quieted for a week then this week started again with screaming about me wearing casual clothing to a retail interview, then triangulated biological ndad to try to manipulate me (your poor mother, stop being stupid - exact words like that), then she forced me to eat vitamins again, she then stole my phone, searched through it again, then deleted her own contact to try to lie and gaslight that i "muted her contact so go unmute it" but she was trying to delete it and make it look like i couldn't find it (growing up, she always purposely hid things, told me to go find it in a specific spot where it's NOT there and gaslight me claiming i was too stupid to find it then she suddenly has the thing she was looking for), she was trying to stress me out and gaslight me and maybe delete evidence of things she said, she doesn't text toxic stuff much to begin with, she's also throwing tantrums complaining about the lack of job offers after interviews and spending money on ubers and threatening to ignore the next time i need a trip to interviews, effectively trying to keep me jobless instead, we are also originally immigrants so she also threatened to rip my legal application for naturalization on the day of the test too

She's trying to drag me to the phone store to force me to transfer data to the iphone in the next few days

she's still being aggressive, no particular reason, even still grey rocking

shelters are full of toxic people with their own stuff and authorities fail their job at all areas (police, etc)

so i have to get work instead, no friends or family to help

what do i do?
