I can get worried at first, but once it's gone away soon after it's started, I know it wasn't an episode: I call it a 'blip' -a bit scary at first, but nothing to worry about. I think, from experience, that worrying can make things worse, so it's best to cut oneself some slack and accept that we can experience a wide range of emotions (even if they really really suck sometimes) but that they're not worrisome in a BP sense. And sometimes, like most people, we're triggered by things going on around us or even our own thoughts that also affect our mood.
