Personality Disorders Support Group
Personality disorders form a class of mental disorders that are characterized by long-lasting rigid patterns of thought and behaviour. Personality disorders are seen by the American Psychiatric Association as an enduring pattern of inner experience and behavior that deviates markedly from the expectations of the culture of the individual who exhibits it.
In North America it appears that the latter person with the psychological problems and the traits of addiction seem to be readily diagnosed as having PD.I don't believe that this is right because the two types of people are different.
Give up on the idea of having a best friend.You need to have a couple of friends 3-4 maybe 5 and to spread your time equally to all of them.Otherwise if you attached to a best friend you'd give all of your time to that person and you'd forget about the others and your relationship with others would suffer.Why? because you have such low self esteem vis a vie those whom you want to be your best friend.Because you want to put them on a pedestal and share intimate stuff with them and attach.If they don't meet your expectations you will get hurt and your view will go the opposite way.If you want to have an unhealthy attachment or a best friend but don't want to get hurt try sharing your intimate or personal stuff with therapist.Your therapist can become that less harmful favorite person until you are well enough ie old enough to do away with that idea entirely.
I'm not sure a therapist can diagnose PD .That diagnosis can only come from a psychiatrist unless the therapist is a clinical psychologist and gets you to fill in a test questionnaire of say 1000-2000 questions which would tell them.
If you are single be careful cause you will more than likely put the person you are eventually going out with or meet in the favorite person on a pedestal category.You will stop hanging out with your friends.You will lose your sense of self in this one person.Its called co-dependency.When it all comes crashing down and you want to reach out to friends will they still be there if you didn't invest in the friendship while in the failed relationship.Its about spreading your energy equally across all people parents friends. Onlt talk to your boss about work related stuff.Keep the personal stuff for the therapist..Tell your therapist that you want to do some work on boundaries and good boundary management.
