It certainly sounds like mania to me as well, and not hypomania like with bipolar II, real mania like with bipolar I. Bipolar is known to worsen over time. And yes, the depression is probably coming -- it nearly always comes after mania. Definitely give a call to your medical professional, whoever that is, and let them know what is up. You're going to need some meds to regulate your moods more effectively. As to the guilt, that I cannot help you with. You need to decide if your marriage can handle the strain of some honesty. I always think that's the best policy myself. If your husband knows you're bipolar, if he knows you've been in a manic stage, he may understand more easily, but it's certainly going to be hard, no matter how the conversation goes. I don't know if your insurance would cover a therapist, but check into it, because you might to better if you had a therapist to talk to who could prep you for how to proceed and help you process the guilt.
Good luck. I'm glad you're coming out of mania -- they can be nightmarish.
