Schizoid personality disorder is kind of an introverted issue where you do not desire to have strong personal relationships. I find this part of my diagnosis weird and possibly incorrect as I do desire personal relationships, I just am very cautious. Also I like to do certain things alone unless I really, really trust someone. I'm not one that actively will go out and make friends, but I still would like friends, but I am very cautious about people and suspicious of them for a long time. (It's actually very complex.)
