Cyberstalking

Only 1 yr in using Apple 13 Pro Max and I’ve been having cyberstalkers somehow using my phone as some kind of remote. Screensharing is off yet I can see someone screensharing and taking pictures of my screen. Also..Some settings seem to be changing on their own. No matter how many times I change my password I seem to have someone accessing my phone through Bluetooth cause that’s when I notice it the most. Please help..I know who they are I need help proving that my phone account is being messed with. I also have pictures of settings that seemed locked into place when I put my focus on. There are certain buttons that won’t turn off or on..seems frozen in place. Please help‼️
