What is rumination

There’s this one situation that I haven’t stopped thinking about from last night . So basically, I was reading 'The power of Now' which is a book that I love so much and really got me into spirituality. It’s been so helpful for my OCD and rumination but it’s also been pretty triggering for it as of late, so I’ve taken a long break from consistently reading it. The excerpt I read was about abundance and how its not about being bountiful, necessarily in material things but realizing and being grateful for the things that exist in your life now and in doing so, you will open yourself up to more good things. I understood it but I re-read it a lot because I didn't feel confident enough to explain it to someone else. but otherwise I LOVED IT. It made me feel so at peace, I agreed with it, and it gave me hope to start focusing on the good things in my life rather than the bad. So when I went to bed I rehearsed myself explaining it to someone on a podcast and then all these questions started flooding in like “why should I only focus on the good and aren't we supposed to accept the good and bad? Aren’t those the values of Buddha and spirituality” “Ya, we're supposed to accept the good and the bad but why?- so we can feel more good??? And isn't the point of OCD to not label things as good and bad? and why should I focus on the good- so I can feel good? why should I feel good? because I'm worthy of it? why am I worthy of it? because I'm a good person and do good things? well I’ve also done bad things so why shouldn't I consider that. I just don’t understand why I should feel good without it being selfish. And then this went on for like 2 or 3 hours. Like holy shit. I over explain these ideas and concepts that I resonate with to the point where they don't even make sense to me anymore. It becomes very existensial very quick. And I’m not suicidal but these questions make me feel hopeless in society for some reason?? And myself. Like if everything contradicts everything then what’s the point to life? If nothing can be understood or explained in a senseful way, then how do people move forward and make decisions, like AT ALL? There’s never a right or perfect answer and I feel like with any decision I make in regards, I’m doing a compulsion either way. If I don’t answer them, then I’m avoiding it and if I do then I’m checking and seeking reassurance. I’m sorry if this was way too long and over-explained I just need some advice or to know if anyone can relate in any way. Also, I’m sorry if some of those back-to-back questions were triggering.

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?

I've been told it's impossible to "push intrusive thoughts away", but also that rumination is a compulsion. What is rumination vs. overthinking? And how do I stop ruminating properly and healthfully?
