the hardest thing has been watching people believe them
So don't watch then. It's not compulsory. Go somewhere else where you don't have to see it daily. They don't actually have magical powers. They're arses, that's all. Shitty people with shitty minds carrying out shitty actions.
You don't have to trust anyone. Go somewhere else and trust nobody. Have conversations with those who've never met you or you them, you'll be blank slates to each other. You don't have to tell them anything you don't want to. You don't have to do anything you don't want to. Wouldn't it be nice to say good morning to the person in the corner shop and for them to know absolutely nothing about you other than that you come in daily for a few bits and always say good morning? Things like that are a place to start from, to regain normal life.
You can choose to stay home all day like you do now though if you prefer. It'll be a choice though, not because you feel trapped. Start small, build an at-home life in the new location without anyone parked outside spying. As you adjust to your freedom you might want to do things outside the home.
