On the off-chance that this is true, your family or a psychologist are unlikely to believe you unless you have some solid evidence.
Why do you believe your neighbours are doing this? Do you have any idea what might be motivating them or whoever is making them do it?
If you do decide to see a psychologist, there's a good chance they'll focus more on finding ways to help you function despite your situation/beliefs, rather than establishing whether or not your claims are true. Might be worth going to an intake session and seeing what they have to offer.
Even if you're imagining this, it never hurts to lock down your devices a bit. You could consider installing Linux or Qubes OS on your PC and a custom rom like GrapheneOS on your phone.
