About 4 weeks ago, I had a bit of an epiphany and changed my mindset and the way I thought about things. I had spent time thinking hard about many painful and shameful memories in the past and then came to realize it really hadn't been my fault at all and I did nothing wrong. This has made me a lot more optimistic, happy, motivated, and confident in the past few weeks.

However, around the same time, I have been not able to fall asleep until very late at night. When I do fall asleep though, I sleep well and for at least 8 hours. But last night, I couldn't sleep at all, spent a lot of time thinking... though I wouldn't say my thoughts were racing. Tonight I can't sleep again even though I didn't get much sleep last night.

Are these signs of the onset of another manic episode? I haven't had one since September 2010. Thanks for any advice.... I can't call my doctor until Monday.
