I lose insight as well, so it's hard to say. One thing I know, though, is that suspiciousness turns into full-blown paranoia. Also, I'm so agitated that I feel like bugs are crawling around inside of me and sounds are extremely amplified (as is light) which makes me very jumpy and irritable. Thoughts become jumbled and I obsess over those thoughts. From there it goes downhill and I have less and less awareness of what's going on with me.
