Delusions are not lies, though. A lie is a purposful act meant to deceive someone. But a delusion is a distortion of reality, so even though most people would not consider it "true" or "fact," it is still not a lie because it is true or a fact to you at that time.

I actually am very honest even when manic and I actually tend to say things I would normally hold back, to be polite or civil. For example, the fight I had with my dad and step-mom at Christmas last year, for a long time I've considered her a gold digger but I haven't said so to her face because it would be rude and put unnecessary stress on my dad. It's not my place to dictate who he marries. But, well, the cat is out of the bag now. Now every time I see them and they have spent money, my dad repeatedly tells me it was his idea to spend that money, because he over-worries about what I think. That's exactly why I held back. So, not a lie, but just trying to keep family peace type of omission.
