First, say that I have been recently diagnosed for third time with strong avoidant traits and strong traits of perfectionism. I always knew I have traits of Perfectionism because the fear of failing made me avoid stressing situations, even when I was perfectly ready to accomplish or face to these situations.

On a second place, I want to say that I know many posts have been written about avoidant personality disorder and avoidant traits. Sorry, I know is different but I want to understand it. I do it for an old friend with the intend to understand the topic better.
I don't want anyone here can have false expectations because of my posts.
I would like to know the opinions mainly from people who were diagnosed with the whole disorder.

The fact that you have the whole disorder means that you could never be with other people in a relationship, or that you can't change your pattern of thoughts and never overcome your self-defense mechanisms?
I don't know. I want to understand.
Thanks!
