OMG! You sound JUST like me! I have never heard of anyone else describe how they must play Solitaire daily until they win (or that they think that winning means that God will give them good luck), or that they can't sleep when they're obsessed with something! If you have what I have, then you're not bipolar, even though you may have some symptoms that mimic it. By any chance, do you feel like you need to know everything about a certain subject when you become obsessed with it, that you have a need to memorize trivia about it? Is it all that you can talk about, and you'll try to bring it up in any context just to be able to talk about the particular subject? Do you find that, when you have trouble sleeping during these obsessive periods, that you have a sort of "excited panic attack," and the only way to get rid of the anxiety is to go pursue the obsession, whatever the method may be? If so, then I think that you might be experiencing a combination of what I have: OCD and Asperger's. In fact, I just went through one of my "obsessive periods" this week. I bought a new video game, and I couldn't rest until I beat it, I had to keep going on the other forum I frequent so I could reach 2000 posts, and when I tried to study, I couldn't focus because I just felt antsy. It's not simply a "lack of willpower," like we can just stop whenever we want. No, it's much more than that. Like, I'll literally waste hours on that other forum because I can't leave until I'm the last poster on each of my main topics, and since many people respond at once, this may take hours. As for the video game thing, I actually slept restlessly on Wednesday night, woke up at three-thirty, and began playing it again, and like you, once I beat it, my interest burns out, and it's just like anything else. The same with music, the same with movies- I'll have to watch/listen to the same thing over and over until my brain stops pummeling me with the images and the sounds. Once this "bubbly", obsessive period is over, then I can relax. Actually, your post also helped me because I felt guilty this past week over not really working as hard academically as I normally do, but I so see now that this was my OCD/Asperger's. So, yes, I, too, experience the guilt you do (just went through that yesterday because I had a test I thought I should've studied more for). I'm on the mood stabilizer Lamictal, which has helped me immensely. If you have any questions, feel free to ask! I'd like to know more to see if you truly do have what I have. God bless!
