That's an interesting thought. The definition of normal becomes a whole different thing in this Bipolar whirlwind!
I would think that "normal" would seem like a mild depression if we were compairing it to Mania.
It's like compairing an average person's life to that of a drug addicted Rock Superstar! Average Joe would seem "boring". But is he boring?? By normal definitions, NO. The Rock star would find him boring though because he's on a different scale, a different point of view.
My son is the one who's Bipolar, I'm just the caregiver. He says that mania is "fun". Yeah, fun for him maybe...But I can see how coming down from all the FUN can be a letdown until you get your bearings. Hense the depression.
Does that make any sense??? I'm not one of those technical/medical posters...I'm just me!
