I'm the same way about sleep! A few weeks ago, I couldn't sleep well for two nights. I felt physically like I had a bad case of the flu-severe nausea (couldn't keep anything solid down), hot and cold flashes, fatigue so extreme that it rivals that of my depressions...On very rare occasion, I can get away with 3 or 4 hours, but that almost never happens.

I'm glad that you're getting answers to your question of whether or not you're bipolar (and its effect on your identity). A lot of people believe that bipolar is overdiagnosed. Good luck with the crippling anxiety; that doesn't sound like any fun. At least you now know what your true issue is, and can work towards addressing it. High dose antidepressants can be helpful for anxiety, and if you're not bipolar, you can take them!
