I saw someone post something like this here when I was googling this, but the person did have diagnosed disorders. From what I know, I don't have any diagnosed mental illnesses. But I do have intrusive thoughts.
I've had them since I was young; most likely high school. I have intrusive thoughts about many things, whether they involved sexual thoughts about people higher above me (they weren't even attractive to me), thoughts about hurting my dear kittens which I would never want to do, thoughts of insulting people I love to see their reactions, other horrible thoughts that I'd rather not say... They always did bother me, and I was always terrified that I would act on these urges. I always thought of myself as a terrible person and a monster for thinking stuff like this, and I never knew this was an actual ailment until recently.
Thing is, like I said, I'm not diagnosed with depression, or anxiety, or OCD or anything really. Then again, I was only really tested for anything once, and that was for ADHD when I was like five (which, turns out I didnt have it). But other than that, I haven't gone to a therapist or a doctor like that ever. So I have no idea where this problem is stemming from. I'm afraid of telling my mom because... well, I don't really know. She just seems very certain that there's nothing wrong with me and it's just something I have to live with because "everyone has these thoughts sometimes." Which I get, but... I've had these kinds of thoughts for five years now, and because of them I just feel super uncomfortable when I'm with my manager (because, of course, those certain horrible thoughts moved from one of my teachers to my current manager at work. yaaaaay) and it's just... horrible.
I guess what I'm trying to ask here is; does everything I explained here seem like your average intrusive thoughts that everyone has? Can intrusive thoughts as severe as they come be without a diagnosis of anxiety or depression or OCD? I don't really know what else, I guess I just really needed to talk about this..
