Drowning in a red state.
If I'm able to notice it then its definitely abnormal. My puberty mood swings stopped at around 13.
You don't have bipolar disorder. You have teenager disorder. It's curable with time.
For Example: I could be completely hating something 1 second, then a few hours later or the next day I want to know everything about it.
Some days I'll give someone a hard time for the simplest things and some days I'll be easy to ask favors of. X_X
