What happened to that person???

Let's take a look at some of the personality disorders, as they are called.  Some people can recognize that they are having a problem, others like to blame their problems on others. 
Someone who is paranoid, will have feelings of mistrust and suspicion of others.
Someone who is schizoid is not schizophrenic, but has some characteristics, that include social isolation and limited range of emotional expression.
Someone who is schizotypal is getting closer to being schizophrenic but not quit there.  This person is like the schizoid but they are having delusions (seeing or hearing things that normal people consider to not be there).
Someone who is antisocial has a disregard for the law and the rights of others.  They have a tendency toward deceit and manipulation.
Someone who is considered borederline has a impulsive and violable personality.  They have a pattern of unstable relationships and are often self-destructive or have suicidal tendencies.
More on this later....

Just know that LENS can help with these problems.
