Is OCD like the fire triangle? Opinions please?

How do you know if it is OCD or just anxiety caused by inner conflict that needs to be resolved? Thoughts - discussions?

Another way to describe it is a loss of ability to let uncomfortable thoughts flow through our minds. It's like a fire alarm going off in our heads and an urgency to work out what these thoughts mean and what we can do about them and it's the exact reason why going to talk therapy is the worst thing that someone with OCD can do.

Hi! It’s pretty difficult for me to get the courage to post this but I’m really struggling to figure out if what I’m experiencing is OCD or Anxiety or neither. I think I have the “pure O” type of OCD where most of my compulsions take the form of ruminating and trying to figure out something all in my head. When I hear this talked about in forums or online the intrusive thoughts don’t really match mine- I worry often about things that seem more “grounded” if that makes sense. A common one for me is my own identity- i will spend long amounts of time stuck in my head trying to figure out my feelings (often sadness or other real emotions I have and patterns I have) and why I feel that way and what in my life caused that and how it’s impacting other things in my life. I also think often about which parts of my personality are the real me and which aren’t. Sometimes this takes the form of strictly ruminating and sometimes I have fake conversations with people I know. It’s intense and I feel I have to figure it out but with no specific intrusive thought that says something like “you have to figure this out or all of your loved ones will die” but it’s very intense. I think also often of all of the decisions I need to make in the future and how they’re going to affect those I love and care about as well as how much I’ll regret them. I imagine all of the ways I think my actions will emotionally hurt others and how to make the least harmful decision, but to me this feels like a valid concern but go over and over and never come to a conclusion. I often just get scared and never make any move because I don’t see an option that doesn’t hurt someone somehow. But again I’m having a hard time identifying the intrusive thought behind it. But I also don’t choose to think about these things most of the time. This is almost all decisions but especially big life decisions. It’s such a struggle because they are things I eventually do have to make decisions about. There is so much more to it that would take too long to explain but in general a lot of my fears revolve around pleasing others/ understanding others emotions to ensure they’re okay, my own identity and personality, and work/school performance. Someone mentioned OCD to me because in my head it feels like I have to solve these things and will go over and over them but I seriously can’t figure out if it’s anxiety, OCD, or none of the above. It’s all very disruptive to my life. I am never not thinking or not trying to figure something out and I feel as if I have no control over it Anyone have any insight?
