Another place to research at Caregiver's Support forum, on the forum page with a list of all the forum topics.

There also a thread in the Schzoid Personality Disorder, the first thread called Welcome to the Schzoid Personality Disorder forum. If you read through those posts, then you can get info that will help you.

At the very top of the page are different topics try the "Conditions" icon, like click that icon, there may be general info on Schzoid Personality Disorder. Also horizontally to that Conditions icon, there is the Resources icon and explore the personality part of that section for more information.(They have a list of support groups including at least one for Schzoid Personality Disorder.)
