How do you know if you're in the midst of (or going into) an episode vs having a really bad or really good day? How do you know? Do you have to wait and see how long it lasts? Do you go by to what extent the symptoms mimic what they usually are when you have been in an episode in the past?

I'd say some semblance of both of the above, that's all I can come up with. What do you guys think?
