This actually seems to be a better overall fit than the OCD he seems to have been diagnosed with, although the OCD symptoms do make me go "hmm maybe" in parts. What is interesting is that OCD is cited as a possible strong comorbid presence in bipolar disorder, so it could very well be that Eric suffered from aspects of both and that they exacerbated each other. The Wikipedia article on Bipolar II disorder actually states that the use of antidepressants may precipitate relapse in patients. This would correspond with my belief that his medication actually made the problem worse. Still, it's pretty much impossible to tell if he suffered from any type of disorder. Not even that which he was diagnosed with is an absolute certainty. As far as I can see now, it is entirely possible that he had bipolar tendencies at the very least. I'm hesitant to actually state that this is absolutely the case, because I've never met the guy and I don't know what he was like on a day-to-day basis. He could've suffered from this, but he also could've suffered from OCD or something else entirely. (Or he could just be like yours truly, you know, where things like racing thoughts are just part of the package and they only get annoying when you're trying to sleep or trying to refocus your patterns on something else. Still, the fact that he was bothered enough by them to mention them in his diversion questionnaire does say a lot. These things are only a problem when they obstruct a part of your everyday functioning self, which he obviously felt they did to some degree.)
