When he applies for a promotion at his job, DeShaun is very disappointed when he doesn’t get it. Talking with his supervisor the next day, DeShaun learns that the promotion committee did not feel that he is capable of making decisions independently and that they see him as a follower and not a leader. As DeShaun is listening to this feedback, he continually nods, agrees, and says things like, "You’re right. I know." At the end of the meeting DeShaun says, "Well, you guys know best so if you don’t think I’m the right person for the promotion, that’s probably a good choice. I’m just glad to have a job here." Based on this description, which personality disorder might DeShaun be diagnosed with?
