Thank you for your response, Perna.

Indeed, my thinking is not logical and I understand this now. However, I don't have that nurse tonight so that might be why I feel OK. I took my meds fine today. I understand that logically that nurse probably wouldn't have poisoned me...but yesterday I felt so sure, so scared.

I'm just so tired of sometimes having that black & white thinking...it makes me feel so mean sometimes when I judge others, but at certain times I feel so sure that some people are evil. :/ It happens more when I'm anxious as well.
