My thoughts doesn't feel intrusive, it just feels like they are there, constantly, chronically, not as pop ups, they are just there, CONSTANTLY. is that intrusive thoughts or something else

Any one else deal with this? Like from the moment they wake up to the second they fall asleep, the intrusive thoughts are there?

for me, it's like there's two folders of my thoughts, 'main thoughts' and 'sub thoughts' and it's like a background voice of my background voice, you know? like so quiet and irrelevant but it's still here and i can try to ignore it but not fully and it feels like it's just really nasty, like it's warring with me, never shuts up and just keeps nagging me with those thoughts

Please how can an intrusive thought be distinguished from our own thoughts ?
