I agree with Sometimes.
I don't have an OCD dx. I have bipolar with generalized anxiety disorder, but I have what I call "thought loops." They are generally things that cause me a lot of anxiety and I have to resolve them in order to move forward. I just get stuck. Often they come along with impulsive or compulsive actions. It's not ritualized at all, but often requires I do research online. The thought loops are not completely irrational at times, but often are over reactions. But clearing them from my mind and resisting the impulses to research is really hard.
Also, I have intrusive thoughts regularly. They are usually violent and not like my usual personality at all.
