My iPhone has been hacked

My iPhone is messed up I believe by a keylogger bc every account password changes almost as soon as I go in and do it. Or I get locked out of my own accounts but I see someone with a “Mac” is still accessing them and an old gmail I tried for months to regain access too after a car wreck & losing access to all devices I was logged in on. To this day I can not get access to it to close it. I get a message that says too little information log in on a known device for this account. I cant my recovery phone number and that device were destroyed. I had to get a new number. I notified Google gmail of this but still locked me out indefinitely. I don’t know how they can give my access to some stranger though. Who is ruining my life & every current account I have now. Stolen my SIM card as well all I can do is call out to static and Iran people when I try to call to pay my credit bills. Which I had a perfect report on. Now I don’t bc of this crap.I noticed last week started with Netflix on my kids tablet. Which I had screen time linked and family to my master iCloud account I noticed every setting was changed to like bad stuff explicit adult ect shes 7. I freaked out yanked it up and checked it was luckily still on kids YouTube at the time thank Heavens. I changed everything bk to how it should be changed mY password & hers & logged out. Log on to our smart tv to find a message from Netflix stating too many devices on our acct they had limited our access! & we pay premium access. Oh I am furious by this time. I check the devices list sure enough full. We only had 3 devices always connected to it. So I clear it. Then all my devices start alerting like musical chairs from the underworld pinging this change that change nonstop & it’s been that way for 7 days.until they shut my notifications off completely. Green dot orange dot always on on my screen top corner. Idk. I’ve had my phone in lockdown since. They can still change my iCloud password my accessibility the list is endless. I call out it’s the same Iran jerks trying to trick me. This Mac never shows up on my linked devices but my old gmail did once, I kicked it off my iCloud but idk how they accessed it first time. It’s still happening & they are using my daughters iPad to change like purchase settings on my account, it’s giving me anxiety. They have stollen my data, wifi at home, my phones hotspot I use for my kid when traveling all gone. It just renewed too. They can turn my Bluetooth on & off & airplay & drop. Which I had used with Apple TV & my tv. It prob is all related but what can I do to stop it now??? All passcode protected. I don’t receive calls. I don’t recieve my texts I have mounds of texts being deleted that I didn’t delete. And my backups are deleted. My kid starts school in a week and a half & her bday is the next day. I hate this!
