The fact that you suspect something is up even if you can't pinpoint what it is probably showing some insight, even if that's not what it feels like(!) You can list symptoms. That's something. I agree with the others about staying safe and contacting your people to try to figure out what is going on.

My psych says I have good insight. Uhhhh, ok. Sometimes. But also very much DON'T have it sometimes. Like emomom, I can have trouble recognizing hypo/mania, and a particularly hard time recognizing mixed. It was more than 2 weeks into the most hellish episode I'd ever had before it even crossed my mind(!!!) It would have been blatantly obvious to anyone looking in from outside the storm (alas, psych was 3,000 miles away). Sometimes our minds are so busy just trying to deal with each moment that there's no room to step back enough to see what's going on.
