I've read a lot about bi-polar disorder, (and from seeing the sleeping habits and just the random bouts of happiness/depression I have) i'm wondering if I might actually have it. Honestly there are times when I just get this feeling from random happiness, it's not even like euphoria.. I can feel it all over like it's within me.. A.. Warmth starts from my forehead and spreads out, washes over me so to speak and when it does it I get happier than I would while impaired by any drug or drink.. :\ and it'll last for a couple of days or so and then I either really get depressed or I get angry/irritated with most things (even people and things I normally love). It wouldn't be that weird of a feeling if I didn't feel like the chemical changes were as obvious as they are, but I know whatever is wrong with me isn't normal because it doesn't happen just from anything occurring in my life, it happens on its own. Does anyone have any suggestions of what might be the problem?
