Absolutely. Talking myself out of feeling ok about something when logically I should. Posting something and then thinking that it was all a mistake, stupid and feeling like taking it back down and so on - things like that. Or even worse, feeling some certain way and then actually questioning or arguing with myself whether I really feel taht or not.

Interestingly, about your taking down your things on your profile. I've done that 2, maybe 3 times now. You'd be surprised also at how many others have done that exact same thing here also in fact I know of a few that actually won't even take friend requests anymore...
