I've been happy and sad off in on in my life. I get really angry easily, but I can be really sweet too. My boyfriend thinks it's weird how my mood is like that.

He says "you're amazing" then the next say "We're over" and my eyes start watering even though I know he's kidding. He purposely does that just because he thinks it's weird. He always calls me bipolar.

He says it might be a word that begins with H. It's like hy-something. I just can't think of it. Anyone have any ideas of what my problem may be? Or is it just normal?
