All day rumination

Hi everyone, I’m new here, and I wanted to share my experience. I’ve been struggling for over a year now on obsessing over a mistake. And the rumination of the mistake I made has been overwhelming and exhausting in those two years. I feel like such a horrible person. At the time, I didn’t realize what I was doing would affect me so much. When I realized it was wrong, I just said I’ll never do it again, and I moved on. But then months later, I was reminded of what I did, and I felt like I did the worst thing in the world, and that my life will never be normal again. And ever since then, it’s been a constant thought. And it’s exhausting. I have been able to open up to my family and a close friend about it and their reactions were so nonchalant compared to what my brain has been telling me. They say it wasn’t even that bad, and that I shouldn’t be beating myself up. I tell them how badly I feel and they just act like it was nothing. I thought that would help, but my brain continues to tell me how horrible of a person I am and I obsess over this one mistake I made two years ago. I’ve learned from it, I’ve moved on, I’ve opened up about it, I’ve gotten reassurance, but yet it still eats at me. It’s constant some days. Where all I wanna do is lay down in a corner and never leave. I feel like my life will never be normal again and I’ll never experience happiness again. Whenever I smile or feel any type of joy my brain tells me to stop and reminds me that I’m a bad person and I don’t deserve to be happy. Even though everyone tells me what I did wasn’t even that bad. And that it doesn’t make me who I am. But guess it’s not enough and I’m really running out of options.

My OCD has become so bad and I feel so alone. I have religious OCD (Christianity) and I’ve been doing okay with letting the blasphemous thoughts go in the moment, but I’m so overcome with guilt and shame I can barely function. I can feel okay and hopeful for a few minutes and then I’m reminded of the horrible thoughts and how nothing can take them back and I can’t handle the guilt. I’m becoming a burden to my family and feel so alone. I do not know what to do. Please help.

I ruminated too much this morning and got distressing mental images (and confirmation) which sent me spiraling again. How do I stop thinking about this and how do I get back to myself? I feel destroyed.
