I believe in psychology this is called white and black thinking. It's one of the many red flags I've found reading your comments. This idea of labelling people 'good' or 'bad' based on a single minimal interaction is also a red flag. I suggest you see a mental health professional - it's hard to live like that. I know there is stigma associated to it in the USA and other places, but if you want to get better that's probably the only way to do so.

Here's to hoping you seek the help you require.
