Looking at people through the lens of seeing all people as all "bad" or all "good."

I had an appointment yesterday to see my psychologist I have been seeing on a weekly basis for about 10 months now. I have borderline personality disorder and bipolar disorder. We focus mainly on communication skills lately. Today I thought it was interesting that my psychologist did not want me to look at people as all "bad." He said specifically to me that when I have bad experiences with certain individuals who are consistently, on a regular basis, always acting in ways that are not respectful to me or who are hurtful toward me, then, that is a red flag that I should stay away and or create healthy bounderies with them; however, there are many who are going to display sooner or later "bad" traits but not always. He also pointed out that I fit into this catergory too and so does he. Now these types of individuals may be worthy to have around maybe even as friends. My psychologist said that he did not want me to look at people through the lens of seeing all people as all "bad" or all "good." This is the hallmark of someone who has borderline personality disorder and this type of thinking causes mood swings, anger, frustration, and depression.

My T advised me that thinking in "absolutes" is a big no-no. Absolutes are sentences that include words like "always", "never", "all", "none", "nobody", "everybody"...

... life is full of exceptions and anomalies. I have to accept that.

Im trying to learn more about this disorder and was wondering if anyone could give me some insightful info?

I've got to work on this tendency as well. I am either quick to categorize people or put up with those that hurt me.
