It's definitely important that you discuss your concerns fully with your psychiatrist. I understand the situation of suddenly not mentioning certain things when finally in front of my therapist or doctor. I often get side tracked or only speak of what's going on "in the moment". My suggestion is that you write what you wrote down here (and any other details) and make sure you bring it to your next appointment. Make sure you mention them, or even give your doctor a print out and ask her to read it briefly to start a discussion.

You're right we can't diagnose here. I'm definitely not qualified. I will say that I have experienced anxiety, irritability, and agitation in depression. From what I've read, these can also appear in major depressive disorder, as can insomnia and hypersomnia. Those symptoms are not exclusive to bipolar disorder. It's really best for a psychiatrist to analyze if these are just features of your major depressive disorder or something else. If you've noticed these symptoms after going off of a medication, that's a very important thing to mention. Do be honest about when you stopped them and how long afterwards such and such symptoms started. How does that compare/contrast with when you've been on your medications (and which medications)? Maybe create a timeline.
