Jonathan should try to figure out what exactly bothers him about his background, and whether this is fair. He could also try to change some of the things he dislikes. If he realizes that his complaints are unfair, he could try to look for groups that are very accepting, or that have a lot in common with him, and try to join these first. If none of this works, Jonathan could try to talk to a therapist who might be able to help him work through these negative feelings.
