And teen angst, when it's constant... is a terribly annoying thing. But, you know, being a teenager, starting your life, hormones and $hit... it's pretty rough. So, you get these strange moods. But, as long as you're not a complete beeyotch and let your emotions control you, you'll be okay. It's okay to have a bad mood, but slitting your wrists is a bit extreme. Having the rational thinking of 'everything has an end, be it bad or good', is a good think to keep in mind. When you're down, you're down. Take your time, deal with it, and go back to your life.
