Well, imagine you've done something very wrong, but at the time you were totally and completely able to justify your actions, and completely believed yourself right, to the point where you could maybe even convince others that you were justified.

Are you lying, or are you believing in a different "truth" that is not widely accepted? Because remember, values are subjective.

That aside, I've absolutely left certain actions, events, and impulsive moves out of therapy sessions in order to avoid discussion and admonishment. I've certainly done things I'm not necessarily proud of. And it would be better to lie about them because the truth would actually be more devastating. I've also done a lot of things "normal" people would be ashamed of that I'm completely honest about. Promiscuity? Totally guilty. Would my parents fair better if they continued to not know about all the different drugs I've done, or the things I used to do when I was drunk? Absolutely.

Do I consider myself honest and trustworthy? Yes. Because at my core, I am. Do I get off on deceiving people? No. It's often necessary for damage control.

So, to your question, does bipolar cause people who are normally honest and trustworthy to lie and be deceitful? I don't think it's intentional. I don't think it's malicious. I think it's a means of protection, not just for oneself but for others. And I think there's a stigma developing here that needs to be addressed.

Now what I want to know is what was in between the ellipses in the following quote:

"Bipolar Disorder can be associated with low serotonin levels, which has been implicated in impulsivity, which...makes a person more prone to lie."

There was something after the "which" and before the "makes" -- what was it?
