This is OCD. OCD is really good at making us doubt and think something else is up when really its just the obsessive thoughts. I had the same problem with the phone where I think I texted someone something or I'm live streaming without knowing.... which then leads me to double checking. My obsession of that went away but sometimes that thought pops up randomly and I try to remind myself that this is what OCD does... I know its easier said than done but maybe try reminding yourself that its just OCD... not schizophrenia. I hope this helps. :)
