A good friend described similar issues. From "them" following him when driving, people hiding in walls, being the target of network snooping and key logging. Schizophrenia/Paranoia. Ended in a hospital telling doctors somebody was trying to kill him at night (there were cameras, nobody was there of course). He eventually got help and medication. You might not think or expect this answer: but get professional psycological help. "They" don't exist. "Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself (i.e. "Everyone is out to get me")." https://en.wikipedia.org/wiki/Paranoia https://en.wikipedia.org/wiki/Paranoia
