Ocd or me?

Does anyone had or have the existential fear of our brain functions. I have so much hyperawareness in my thoughts, I focus all the time in my feelings and my intentions in order to check if I am strange or not and if I have control of my actions. I do psychotherapy 4 years and I thought I was fine. But this June I had a derealization episode(or ocd) , after that a depersonalization episode (or ocd) and after that I have obsessions about our existence and that every aspect in our lives has to do with our brain and for some reason these thoughts scary me. I know that at some point is ocd but I am very confused why this thoughts scary me so much. I observe others and I am curious how it's possible not to think about that and this make it worse . I am so anxious because obviously we are our brain ,I know that and brain has to do with everything,but I don't know why it make me anxious and if it's possible to live without these thoughts. I do many compulsion but my biggest is to figure out if I have compulsion in order to figure out if my thoughts is ocd or delusions. It's so real and these thoughts really bother me. Any other with same experience?

How can I tell the difference between suicidal ocd and suicidal thoughts?

I'm reaching out in hopes of finding others who might relate to my experiences or offer insights. I'm dealing with a complex interplay of OCD, depression, and existential anxiety, and I'm struggling to make sense of it all. Here's what I'm experiencing: I have OCD with various manifestations, along with episodes of depression. I find myself in a cyclical pattern where, after a few weeks, I start to remind myself about my depressive tendencies. This reminder seems to trigger a cycle that actually makes me feel more depressed or at least more aware of depressive symptoms. When this happens, I often experience feelings of nihilism and existential dread. I try to think about my family - my two young boys and my wife - to find motivation or a sense of purpose, but this strategy often backfires, making me feel even more anxious and depressed. I constantly check my feelings, wondering if they're depressive or anxious. At the same time, I fear that my feelings of anxiety and panic might spiral out of control. I think about my emotions and thoughts on a meta-level, which means I'm not just experiencing feelings, but I'm also constantly analyzing the fact that I'm experiencing them. There's an existential component to my struggles, a fear of depression and anxiety itself, and a sense that this might be a self-fulfilling prophecy. Perhaps most frustratingly, I often have feelings, thoughts, or sensory experiences that I can't explain or put into words. I feel like I've never heard of these before, which leaves me feeling deeply misunderstood. Does anyone else experience something similar? How do you cope with this complex web of symptoms and experiences? I'm particularly interested in hearing from those who've found ways to break the cycle of meta-cognition and self-fulfilling anxiety. Any insights, shared experiences, or strategies would be deeply appreciated. Thank you for your time and understanding.
