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

I have comorbid bipolar disorder and OCD. I can’t take SSRIs or SNRIs because they destabilize my bipolar disorder and act against the meds I’m taking for that. Does anyone have experience with non-serotonin-based medication for OCD that has worked for you?

Question: Given the differences of OCD and depression, how do you balance not seeking reassurance with comfort from others that you will be ok? Context: Hi all, I’ve recently found it challenging to manage both OCD and depression because I feel they require different strategies. I’m feeling managing OCD requires you to not seek reassurance, but at the same time, depression seems like you need someone to just tell you “it’s going to be ok.” Recently, I’ve been trying to not seek reassurance, but I feel that I’m not able to make the best decisions that way, and the weight of those led to a longer depression which includes intrusive thoughts that are hard to manage. I describe the relationship as a Venn Diagram, but OCD is on the top and depression is at the bottom, and the intersection is the threshold/breaking point that can lead to longer depression. Any advice from experience or perspectives that people can offer? I appreciate it.

Anyone experienced something like this? I was never diagnosed with depression. However lately idk if my ocd is trying to latch on another theme but its questioning whether or not im depressed. Im scared of depression. The feeling in my stomach makes me think its depression. But the same feeling in my stomach is also one I feel with OCD flare ups. I did research symptoms of depression and was self checking. Anyone else experienced this?
