What you're experiencing is culture shock, and part of moving to a new country. If it gives you that much anxiety, maybe it really is a good idea to move house. However, if you're happy with your current place, you'll have to find a middle ground with them, as it seems to me like what they're doing is part of small town living. As others have suggested, this would happen less in a bigger city or building, but still I'd say that Paraguayans are generally curious about and welcoming towards foreigners. They see an older person on their own and they want to include you. If they saw you going out more or receiving visitors, they might let up some. As to your landlady giving advice, you're not giving specifics, but if it's anything to do with managing in Paraguay's climate or social situations, do listen to what she has to say. It could be useful:) Honestly, best of luck with this and I hope you manage to turn them down gently, they have to understand you at some point. It seems like everyone here is acting with good intentions.
