I find myself falling into extreme paranoia for a couple of days and then be absolutely fine afterwards. Nothing really triggers my paranoia (at least not that i know of), but when it happens it prevents me from doing the simplest of tasks cause I'd get panic attacks from it. 

I'd start seeing figures and hearing things, it's a nightmare when im home alone cause i genuinely feel like someone's there. I can't go out during this time either cause i feel like people hate me and are gonna hurt me and being outside of my room gets overwhelming and would often result in panic attacks. It happens a few times in a month but i can never gauge when it'll hit. Is this a bpd thing or is it completely unrelated?
