Mental compulsions taking over

I’ve been through a lot of trauma the past few months and years and had an anxiety breakthrough where I can’t stop having panic and anxiety attacks. I used to be a horror movie addict and one night during an anxiety attack my brain went “Kill your sister” My sister is my whole world. It all went downhill from there. I can’t even be around her when were home alone anymore. Every single day since then my brain is trying to tell me a bunch of different ways to harm her. Its getting to a point where its involving others now. “Kill your sister.” “What if you finally go back to your boyfriends house and kill his family?” “What if you kill mom?” “Kill that lady walking down the aisle at work.” “What if you killed yourself?” “You’re a bad person for thinking all of this.” “You shouldn’t be allowed to sleep, eat or relax. Bad people don’t get to do those things.” “These thoughts are in your head 24/7 because you WANT to do these things!” Its causing me so much anxiety and racing thoughts and I don’t want to become anymore depressed. SSRIs dont work. My doctor wants me to go on antipsychotics but I’m afraid to and I feel like I don’t actually need them and it will cause more damage. My goal is to become the person I was before all of this. Not to change completely. I tried buspirone once and I stopped due to increased health anxiety and often found myself saying “remember when you wanted to kill your sister?” and then brushing it off. It helped in some sort of way. I was only on it for a week. My whole life has changed since then. I dont go to my boyfriends house anymore, I dont see my friends, I can’t play video games anymore. All I do is ruminate and I cant stop. I cant even hold a conversation anymore. The compulsions are horrible. I’m so scared that theres no coming back from this. Its all adding to the anxiety that I don’t want to become severe depression. I just want to be me again. I’m starting off ERP and if it doesn’t work I dont know what to do. Can someone please tell me they have been through similar and have gotten better. I just need to save my life. Its getting to a point where this is convincing me this is all real and its going to happen and that im gonna become a psychopath. Its been going on for 3 months. I used to be so bubbly and happy!! (I am not schizoaffective)

So I've been working to address my OCD for about a month now. So far, I haven't been working on it with a therapist and have instead been trying to create my own exposure exercises. The primary obsession I'm working on is the fear that I'm somehow flawed or invalid on a fundamental level. The best way I can describe it it is that its similar to the feeling you get when you have germ OCD and you feel contaminated, except my whole existence and being feels contaminated, so to speak. I've identified a list of triggers, and a list of compulsions (pretty much all mental) that I've noticed myself performing. I started out by doing imaginal exposures and scripts where I'd write out triggering fictional scenarios and read them over and over, combined with mindfulness techniques to focus on my breath and bring myself back to the present when I noticed myself performing compulsions mentally. At first it worked to some extent, but eventually I started to feel like the stories I was writing about this obsession weren't triggering any anxiety anymore or a very low level. So I stopped reading them and focused solely on improving my ability to stay present and identifying compulsions as I perform them, and disengaging. Now, I'm at the point where it seems like my general anxiety levels throughout the day are lower, and the triggers I've identified are producing noticeably less anxiety. But that makes me wonder if somehow I'm just secretly doing mental compulsions without knowing it? Is only a month of rather disorganized and unstructured ERP enough to produce this much improvement? To avoid giving me re-assurance, I'd appreciate if you guys don't directly answer those questions, maybe just provide some possibilities or your own experiences so I can get a better idea of where I'm at. Any info would be appreciated. Thanks!

So been trying to do erp with my therapist for a while now, and tis really hard and feels like it's not working. Il get this weird sensation or feeling that makes me feel"gay" or as if I'm attracted to someone, and I know my therapist keeps telling me" you don't have to put meaning into the thoughts or feelings" but that seems impossible to do because and I'm sorry to say, it makes me feel that specific way. And I'll use the Erp quotes, "maybe maybe not" or"the more I struggle, the worse it gets" or"these feelings and thoughts are here, but I'm choosing to let them be" and I'll do nothing and try to let it be here but it's so distracting and feels very real, and it's like this sensation, small or big and it last all day, and even just sitting with it isn't working. And my therapist will tell me"you don't have to believe in it" and I'm sorry I feel like if it were that easy, OCD would have never been a problem in the first place, or live with uncertainty, however it doesn't feel like uncertainty, but feels very truthful or valid. Idk what I'm doing wrong tho
