Does anyone have any comorbidity including bipolar disorder or depression? How can you differentiate the depression caused by OCD from potentially another issue entirely?

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.

I went through ERP which helped a little but starting ICBT to hopefully help with rumination. I deal with suicidal ocd mainly which originally was a lot of specific harm thoughts and has now turned into “do I wanna do something” “am I depressed” and over analyzing everything that has to do with mental health. I’m on 20 of Prozac, have been for a couple months. My anxiety has almost went away but this week I’ve been concerned that I’m developing depression (for the first time ever), but I’m just not sure. I feel off. I feel “blah”. I’m worried that I’m not caring as much about things I did before. I’m ruminating a lot. Does anyone have any advice or insight? It’s really bothering me. I don’t want to freak out over this but want to prevent depression getting bad.
