I think it's fantastic that you have created a theory on the subject, as it's a very interesting and relevant one. However, I'd have to disagree with it. It seems far too generalized - expecting everyone with Bipolar Disorder to have had issues with repressing emotions during their childhood. It's just not realistic. I think with all mental illnesses, some had difficult childhoods with emotions repressed, and others didn't. We can't lump everyone into a certain category.
