Personality disorder. Personality disorders are long-term maladaptive patterns of thoughts and behaviors that cause distress. There are many types with variable symptoms. Seeing a mental health professional for an evaluation would be the best way to proceed.
Ask a professional. I would go to a professional to find out. Diagnosing personality disorders is highly specialized and takes a great deal of experience. I wouldn't rely on books or online tests to provide you with an answer here.
Eval. Get a full psychiatric evaluation to determine what bothers you. Consider the benefits of medication. There is a personality test known as the Minnesota multiphasic personality inventory and that can be administered by a psychologist, that can augment the findings of the psychiatrist.
