What happens during an episode of OCD?

So I've had OCD since I was a child. Like really young. The first intrusive thought I can remember was when I was 5. It just keeps getting worse and lately they've been making me physically ill or throwing me into extreme panic attacks again ( ones where I can't move my body ) the other night I thought God was trying to kill me because I was thinking about ending myself from OCD+ life issues but in reality I was just having a panic attack😭😭it affects me daily. It gets a little better with therapy but I don't see therapy coming into my life any time soon and I'm not even sure if I would want to go (for multiple reasons). To wrap this up if you have severe ocd can you tell me what it's like?? I don't want to label anything without proper research and hearing others perspectives. Thank you!! <3 (My profile says all of my subtypes if that helps any)

My OCD has never been this strong, it's so real, it feels like it will never go away, it's never been this strong for me and it's very scary.

Two things are happening: I get thoughts that just keep looping. They almost feel like song stuck in my head. Also, I’ll imagine something and I feel my stomach drop. Then as the seconds go by I keep getting fragments of the this thought but with different details. For example, it’s kinda like how a “vision” is portrayed. I’ll get a glimpse of the thought and then it’ll rapidly expand into something worse every few seconds. I don’t know if I’m causing this or if it’s just an automatic thing like any other intrusive thought. It feels unavoidable, idk if this is a compulsion or if it’s just another manifestation of an intrusive thought. Apart from that remembering an intrusive thought triggers the full thought again and then it just keeps looping or expanding. I don’t know how to stop any of this. Help?
