Struggling with intrusive thoughts after seeing a horror doll.

Theres been a recent situation thats been eating at my mind, it was 3 days ago i got a really nasty and worrying intrusive thought and at the time i couldnt help withdrawing and ruminating over it. But suddenly i cant stop thinking about it and its making things so hard because i dont want to. But then i start to question why i keep thinking about it and why it wont leave my head. I cant eat or focus on anything else im so scared right now. How do i let it pass, how can i let this kind of thought go or not pass judgement on it. It seems so impossible

So I saw a knife in the kitchen two days ago and my anxiety went off the charts. And my brain is now saying I might do something to my mom. What the hell is going on with me? And now I feel scared, worried and don’t even want to be in the kitchen. So sone help me. What is this abs what do I do??

Does anyone else get the theme of fear of going crazy or into a psychosis ? I’ve been having that fear lately and it has been the worse ever. I’ve never had these thoughts before and I don’t know what triggered them that they won’t go way. I couldn’t eat for days from how scared I was of these thoughts. I keep having intrusive thoughts like what if you’re imagining it for example I was at TJ Maxx with my mom and I was looking for her and when I saw her a thought popped into my head like “what if that’s not her and your imagining it” it was so scary that I wanted to cry. Of course apart of me knows that’s not true but the thoughts keep popping up. I’m so scared and just want to be myself again. So if anyone has gone through this theme can you please tell me what helped you. I’ve also struggled with harm ocd, suicidal ocd and a lot of health anxiety. I can’t afford therapy so if yall have any recommendations on what helped your ocd please let me know. I’m so tired and feel so helpless. I want my life back.
